									<p data-start="836" data-end="1458">The ability to accurately characterize tooth surfaces, including micro-roughness and 3D surface topography at the nanometer scale, enables advanced research and applications in orthodontics and dental materials science. Non-contact optical profilometry provides a precise method for measuring dental surface roughness and analyzing tooth surface morphology without damaging delicate structures. These measurements support the development of composite dental materials that replicate the natural surface roughness of enamel, as well as the design and fabrication of patient-specific dental casts and restorative components.</p><p data-start="1460" data-end="1982">Low surface roughness plays a primary role in limiting bacterial adhesion and plaque formation, thereby reducing the risk of cavities. An increase in average roughness (Ra) above 2 µm leads to a steep increase in biofilm formation in vivo.¹ An Ra of 0.2 µm is considered the threshold value below which no further reduction in bacterial adhesion can be expected.²</p><p data-start="1984" data-end="2182">Reconstruction of the tooth’s 3D surface topography enables the fabrication of dental casts, which are essential for accurate diagnosis, treatment planning, and the fabrication of dental appliances.</p>								</div>

									<p>La pallinatura è un processo in cui un substrato viene bombardato con sfere sferiche di metallo, vetro o ceramica, comunemente denominate &quot;sparate&quot;, con una forza destinata a indurre plasticità sulla superficie.

									<p>A differenza dei profilometri a contatto tradizionali, tradizionalmente utilizzati per l&#039;analisi delle superfici pallinate, la misurazione 3D senza contatto fornisce un&#039;immagine 3D completa per offrire una comprensione più completa dell&#039;area di copertura e della topografia della superficie. Senza funzionalità 3D, un&#039;ispezione si baserà esclusivamente su informazioni 2D, che non sono sufficienti per caratterizzare una superficie. Comprendere la topografia, l&#039;area di copertura e la rugosità in 3D è l&#039;approccio migliore per controllare o migliorare il processo di pallinatura. di NANOVEA <a href="https://nanovea.com/profilometers/">Profilometri 3D senza contatto</a> utilizzano la tecnologia della luce cromatica con una capacità unica di misurare gli angoli ripidi riscontrati su superfici lavorate e pallinate. Inoltre, quando altre tecniche non riescono a fornire dati affidabili a causa del contatto della sonda, della variazione della superficie, dell&#039;angolo o della riflettività, i profilometri NANOVEA riescono.</p>								</div>

È evidente che sia Surface 1 che Surface 2 hanno un impatto significativo su tutti i parametri qui riportati rispetto alla materia prima. Un semplice esame visivo delle immagini rivela le differenze tra le superfici. Ciò è ulteriormente confermato dall&#039;osservazione dell&#039;area di copertura e dei parametri elencati. Rispetto alla superficie 2, la superficie 1 presenta una rugosità media inferiore (Sa), ammaccature meno profonde (Sv) e un&#039;area superficiale ridotta (Sdar), ma un&#039;area di copertura leggermente superiore.</p><p>Da queste misurazioni della superficie 3D, le aree di interesse possono essere facilmente identificate e sottoposte a una gamma completa di misurazioni, tra cui rugosità, finitura, consistenza, forma, topografia, planarità, deformazione, planarità, volume, altezza del gradino e altre. È possibile scegliere rapidamente una sezione trasversale 2D per un&#039;analisi dettagliata. Queste informazioni consentono un&#039;analisi completa delle superfici martellate, utilizzando una gamma completa di risorse per la misurazione della superficie. Aree di interesse specifiche potrebbero essere ulteriormente esaminate con un modulo AFM integrato. I profilometri 3D NANOVEA offrono velocità fino a 200 mm/s. Possono essere personalizzati in termini di dimensioni, velocità, capacità di scansione e possono persino essere conformi agli standard delle camere bianche di classe 1. Sono inoltre disponibili opzioni come Indexing Conveyor e integrazione per l&#039;utilizzo in linea o online.</p></div></div></div></div></div></div>								</div>

									<p>La vernice viene solitamente applicata in forma liquida e subisce un processo di essiccazione, che prevede l&#039;evaporazione dei solventi e la trasformazione della vernice liquida in una pellicola solida. Durante il processo di essiccazione, la superficie verniciata cambia progressivamente forma e consistenza. È possibile sviluppare diverse finiture superficiali e trame utilizzando additivi per modificare la tensione superficiale e le proprietà di flusso della vernice. Tuttavia, in caso di una ricetta di vernice mal formulata o di un trattamento superficiale improprio, possono verificarsi cedimenti indesiderati della superficie della vernice.</p>
<p>Un accurato monitoraggio in situ della morfologia della superficie della vernice durante il periodo di essiccazione può fornire una visione diretta del meccanismo di essiccazione. Inoltre, l’evoluzione in tempo reale delle morfologie superficiali è un’informazione molto utile in varie applicazioni, come la stampa 3D.

									<p>La vernice è stata applicata sulla superficie di una lamiera, seguita immediatamente da misurazioni automatizzate dell&#039;evoluzione morfologica della vernice in essiccazione in situ utilizzando il profilometro senza contatto NANOVEA ST500 dotato di un sensore di linea ad alta velocità. Una macro era stata programmata per misurare e registrare automaticamente la morfologia della superficie 3D a intervalli di tempo specifici: 0, 5, 10, 20, 30, 40, 50 e 60 min. Questa procedura di scansione automatizzata consente agli utenti di eseguire le attività di scansione automaticamente eseguendo le procedure impostate in sequenza, riducendo notevolmente lo sforzo, il tempo e i possibili errori dell&#039;utente rispetto ai test manuali o alle scansioni ripetute. Questa automazione si rivela estremamente utile per misurazioni a lungo termine che comportano più scansioni a diversi intervalli di tempo.</p><p>Il sensore di linea ottica genera una linea luminosa composta da 192 punti, come mostrato nella FIGURA 1. Questi 192 punti luminosi scansionano simultaneamente la superficie del campione, aumentando significativamente la velocità di scansione. Ciò garantisce che ogni scansione 3D venga completata rapidamente per evitare cambiamenti sostanziali della superficie durante ogni singola scansione.</p>								</div>

									<p>La vista in falsi colori, la vista 3D e il profilo 2D della topografia della vernice essiccata in momenti rappresentativi sono mostrati rispettivamente nella FIGURA 2, FIGURA 3 e FIGURA 4. Il falso colore nelle immagini facilita il rilevamento di caratteristiche che non sono facilmente distinguibili. I diversi colori rappresentano le variazioni di altezza nelle diverse aree della superficie del campione. La vista 3D fornisce uno strumento ideale per gli utenti per osservare la superficie della vernice da diverse angolazioni. Durante i primi 30 minuti del test, i falsi colori sulla superficie della vernice cambiano gradualmente da toni più caldi a toni più freddi, indicando una progressiva diminuzione dell&#039;altezza nel tempo in questo periodo. Questo processo rallenta, come dimostra il lieve cambiamento di colore confrontando la vernice a 30 e 60 minuti.</p><p>L&#039;altezza media del campione e i valori di rugosità Sa in funzione del tempo di asciugatura della vernice sono riportati nella FIGURA 5. L&#039;analisi completa della rugosità della vernice dopo 0, 30 e 60 minuti di asciugatura è elencata nella TABELLA 1. Si può osservare che l&#039;altezza media della superficie pittorica diminuisce rapidamente da 471 a 329 µm nei primi 30 minuti di asciugatura. La trama superficiale si sviluppa contemporaneamente alla vaporizzazione del solvente, portando ad un aumento del valore di rugosità Sa da 7,19 a 22,6 µm. Successivamente il processo di essiccazione della vernice rallenta, determinando una graduale diminuzione dell&#039;altezza del campione e del valore Sa a 317 µm e 19,6 µm, rispettivamente, a 60 min.</p><p>Questo studio evidenzia le capacità del profilometro senza contatto 3D NANOVEA nel monitorare i cambiamenti della superficie 3D della vernice in essiccazione in tempo reale, fornendo preziose informazioni sul processo di essiccazione della vernice. Misurando la morfologia della superficie senza toccare il campione, il profilometro evita di introdurre alterazioni di forma alla vernice non essiccata, che possono verificarsi con tecnologie di contatto come lo stilo scorrevole. Questo approccio senza contatto garantisce un&#039;analisi accurata e affidabile della morfologia della superficie della vernice in essiccazione.</p>								</div>

<p>In questa applicazione, abbiamo mostrato le capacità del profilometro 3D senza contatto NANOVEA ST500 nel monitorare l&#039;evoluzione della morfologia della superficie della vernice durante il processo di essiccazione. Il sensore di linea ottica ad alta velocità, che genera una linea con 192 punti luminosi che scansionano simultaneamente la superficie del campione, ha reso lo studio efficiente in termini di tempo, garantendo al tempo stesso una precisione senza pari.</p>
<p>La funzione macro del software di acquisizione consente di programmare misurazioni automatizzate della morfologia della superficie 3D in situ, rendendolo particolarmente utile per misurazioni a lungo termine che coinvolgono più scansioni a specifici intervalli di tempo target. Riduce significativamente il tempo, lo sforzo e il potenziale di errori dell&#039;utente. I progressivi cambiamenti nella morfologia della superficie vengono continuamente monitorati e registrati in tempo reale mentre la vernice si asciuga, fornendo preziose informazioni sul meccanismo di asciugatura della vernice.</p>
<p>I dati mostrati qui rappresentano solo una frazione dei calcoli disponibili nel software di analisi. I profilometri NANOVEA sono in grado di misurare praticamente qualsiasi superficie, sia essa trasparente, scura, riflettente o opaca.</p></div></div></div>

									<p>I materiali per pavimenti sono progettati per essere durevoli, ma spesso subiscono l’usura dovuta alle attività quotidiane come il movimento e l’uso dei mobili. Per garantirne la longevità, la maggior parte dei tipi di pavimentazione dispone di uno strato protettivo antiusura che resiste ai danni. Tuttavia, lo spessore e la durabilità dello strato di usura variano a seconda del tipo di pavimentazione e del livello di traffico pedonale. Inoltre, diversi strati all’interno della struttura della pavimentazione, come rivestimenti UV, strati decorativi e smalti, hanno tassi di usura variabili. È qui che entra in gioco la mappatura progressiva dell&#039;usura. Utilizzando il tribometro NANOVEA T2000 con un integrato <a style="background-color: #ffffff;" href="https://nanovea.com/profilometers/">Proﬁlometro 3D senza contatto</a>È possibile effettuare un monitoraggio preciso e un&#039;analisi delle prestazioni e della longevità dei materiali della pavimentazione. Fornendo informazioni dettagliate sul comportamento all&#039;usura dei vari materiali di pavimentazione, scienziati e professionisti tecnici possono prendere decisioni più informate nella selezione e nella progettazione di nuovi sistemi di pavimentazione.</p>								</div>

									<p>I test sulle pavimentazioni sono tradizionalmente incentrati sul tasso di usura di un campione per determinarne la resistenza all'usura. Tuttavia, la mappatura progressiva dell'usura consente di analizzare il tasso di usura del campione durante l'intero test, fornendo preziose informazioni sul suo comportamento all'usura. Questa analisi approfondita consente di stabilire correlazioni tra i dati di attrito e il tasso di usura, identificando così le cause principali dell'usura. Va notato che i tassi di usura non sono costanti durante i test di usura. Pertanto, l'osservazione della progressione dell'usura fornisce una valutazione più accurata dell'usura del campione. Superando i metodi di prova tradizionali, l'adozione della mappatura progressiva dell'usura ha contribuito a significativi progressi nel campo delle prove sulle pavimentazioni.</p>								</div>

									<p>I test di mappatura progressiva dell'usura sono stati eseguiti su due tipi di materiali per pavimentazione: pietra e legno. Ogni campione è stato sottoposto a un totale di 7 cicli di prova, con durate crescenti di 2, 4, 8, 20, 40, 60 e 120 s, per consentire un confronto dell'usura nel tempo. Dopo ogni ciclo di prova, la traccia di usura è stata profilata con il profilometro senza contatto NANOVEA 3D. Dai dati raccolti dal profilometro, il volume del foro e il tasso di usura possono essere analizzati utilizzando le funzioni integrate nel software NANOVEA Tribometer o nel nostro software di analisi delle superfici, Mountains.</p>								</div>

									<p>Dove V è il volume di un foro, N è il carico e X è la distanza totale, questa equazione descrive il tasso di usura tra i cicli di prova. Il tasso di usura istantaneo può essere utilizzato per identificare meglio le variazioni del tasso di usura nel corso della prova.</p><p>Entrambi i campioni presentano comportamenti di usura molto diversi. Nel corso del tempo, il pavimento in legno inizia con un tasso di usura elevato, ma scende rapidamente a un valore minore e costante. Per il pavimento in pietra, il tasso di usura sembra iniziare con un valore basso e tendere a un valore più alto nel corso dei cicli. Anche il tasso di usura istantaneo mostra poca coerenza. La ragione specifica della differenza non è certa, ma potrebbe essere dovuta alla struttura dei campioni. Il pavimento in pietra sembra essere costituito da particelle sciolte simili a grani, che si usurano in modo diverso rispetto alla struttura compatta del legno. Sarebbero necessari ulteriori test e ricerche per accertare la causa di questo comportamento di usura.</p><p>I dati del coefficiente di attrito (COF) sembrano concordare con il comportamento di usura osservato. Il grafico del COF per il pavimento in legno appare costante durante i cicli, a complemento del tasso di usura costante. Per la pavimentazione in pietra, il COF medio aumenta durante i cicli, in modo simile a come anche il tasso di usura aumenta con i cicli. Si notano anche evidenti cambiamenti nella forma dei grafici di attrito, che suggeriscono cambiamenti nel modo in cui la sfera interagisce con il campione di pietra. Questo fenomeno è più evidente nel ciclo 2 e nel ciclo 4.</p>								</div>

									<p>Il tribometro NANOVEA T2000 mostra la sua capacità di eseguire una mappatura progressiva dell'usura analizzando il tasso di usura tra due diversi campioni di pavimentazione. La pausa del test di usura continua e la scansione della superficie con il profilometro senza contatto NANOVEA 3D forniscono preziose informazioni sul comportamento del materiale nel tempo.</p><p>Il tribometro NANOVEA T2000 con il profilometro 3D senza contatto integrato fornisce un'ampia gamma di dati, tra cui COF (Coefficiente di attrito), misure di superficie, letture di profondità, visualizzazione della superficie, perdita di volume, tasso di usura e altro ancora. Questa serie completa di informazioni consente agli utenti di comprendere più a fondo le interazioni tra il sistema e il campione. Grazie al carico controllato, all'elevata precisione, alla facilità d'uso, al carico elevato, all'ampio intervallo di velocità e ai moduli ambientali aggiuntivi, il tribometro NANOVEA T2000 porta la tribologia a un livello superiore.</p>								</div>

In FIGURA 2a, il campione di rugosità presenta una superficie leggermente inclinata, come rappresentato dal gradiente di colore variabile in ciascuno dei blocchi di rugosità standard. In FIGURA 2b, la distribuzione omogenea della rugosità è mostrata in blocchi di rugosità diversi, il cui colore rappresenta la rugosità nei blocchi.</p><p>La FIGURA 3 mostra esempi di Mappe Pass/Fail generate dal software di analisi in base a soglie di rugosità diverse. I blocchi di rugosità sono evidenziati in rosso quando la loro rugosità superficiale è superiore a un determinato valore di soglia. In questo modo l'utente può impostare una soglia di rugosità per determinare la qualità della finitura superficiale di un campione.</p>								</div>

La mappa di rugosità mostra una rugosità omogenea nell'area intatta del campione di Teﬂon. Tuttavia, i difetti, sotto forma di un anello frastagliato e di una cicatrice da usura, sono evidenziati con colori brillanti. L'utente può facilmente impostare una soglia di rugosità Pass/Fail per individuare i difetti superficiali, come mostrato nella FIGURA 4c. Questo strumento consente agli utenti di monitorare in loco la qualità della superficie del prodotto nella linea di produzione e di scoprire in tempo i prodotti difettosi. Il valore di rugosità in tempo reale viene calcolato e registrato al passaggio dei prodotti dal sensore ottico in linea, che può servire come strumento rapido ma affidabile per il controllo della qualità.</p>								</div>

									<p>A differenza di altre tecniche come i tastatori o l&#039;interferometria, la NANOVEA <a href="https://nanovea.com/profilometers/">Profilometro 3D senza contatto</a>, utilizzando il cromatismo assiale, può misurare quasi tutte le superfici, le dimensioni dei campioni possono variare ampiamente a causa della stadiazione aperta e non è necessaria alcuna preparazione del campione. L&#039;intervallo da nano a macro si ottiene durante la misurazione del profilo di superficie senza alcuna influenza da parte della riflettività o dell&#039;assorbimento del campione, ha una capacità avanzata di misurare angoli superficiali elevati e non è prevista alcuna manipolazione dei risultati da parte del software. Misura facilmente qualsiasi materiale: trasparente, opaco, speculare, diffusivo, lucido, ruvido ecc. Le funzionalità 2D e 2D dei Profilometri Portatili NANOVEA li rendono strumenti ideali per l&#039;ispezione completa della superficie di saldatura sia in laboratorio che sul campo.</p>								</div>

									<p>Tradizionalmente, i test di abrasione Taber sono stati eseguiti per valutare la resistenza all'usura delle vernici acriliche per pavimenti secondo lo standard ASTM D4060. Tuttavia, come indicato nella norma, "per alcuni materiali, i test di abrasione che utilizzano il Taber Abraser possono essere soggetti a variazioni dovute a cambiamenti nelle caratteristiche abrasive della ruota durante il test".1 Ciò può comportare una scarsa riproducibilità dei risultati dei test e creare difficoltà nel confrontare i valori riportati da diversi laboratori. Inoltre, nei test di abrasione Taber, la resistenza all'abrasione è calcolata come perdita di peso a un determinato numero di cicli di abrasione. Tuttavia, le vernici acriliche per pavimenti hanno uno spessore del film secco raccomandato di 37,5-50 μm2.</p><p>L'aggressivo processo di abrasione di Taber Abraser può consumare rapidamente il rivestimento in uretano acrilico e creare una perdita di massa nel substrato, con conseguenti errori sostanziali nel calcolo della perdita di peso della vernice. Anche l'impianto di particelle abrasive nella vernice durante il test di abrasione contribuisce agli errori. Pertanto, una misurazione quantificabile e affidabile ben controllata è fondamentale per garantire una valutazione riproducibile dell'usura della vernice. Inoltre, la <a href="https://nanovea.com/scratch-tester/">test di graffiatura</a> consente agli utenti di rilevare cedimenti prematuri di adesivi/coesive in applicazioni reali.</p>								</div>

									<p style="text-align: left;">Il tester meccanico NANOVEA, dotato di uno stilo in diamante Rockwell C (raggio di 200 μm), è stato utilizzato per eseguire prove di graffiatura a carico progressivo sui campioni di vernice utilizzando la modalità Micro Scratch Tester. Sono stati utilizzati due carichi finali: 5 N per verificare la delaminazione della vernice dal primer e 35 N per verificare la delaminazione del primer dai substrati metallici. Per garantire la riproducibilità dei risultati, sono stati ripetuti tre test alle stesse condizioni su ciascun campione.</p><p style="text-align: left;">Le immagini panoramiche delle intere lunghezze dei graffi sono state generate automaticamente e le loro posizioni critiche di rottura sono state correlate con i carichi applicati dal software del sistema. Questa funzione del software consente agli utenti di eseguire analisi sulle tracce di graffio in qualsiasi momento, anziché dover determinare il carico critico al microscopio subito dopo i test di graffio.</p>								</div>

									<p style="text-align: justify;">Su ogni campione sono stati eseguiti quattro test di usura pin-on-disk a diversi numeri di giri (100, 150, 300 e 800 cicli) per monitorare l'evoluzione dell'usura. La morfologia superficiale dei campioni è stata misurata con un profilatore senza contatto NANOVEA 3D per quantificare la rugosità superficiale prima di eseguire i test di usura. Tutti i campioni presentavano una rugosità superficiale comparabile di circa 1 μm, come illustrato nella FIGURA 1. La COF è stata registrata in situ durante i test di usura, come mostrato in FIGURA 2. La FIGURA 4 presenta l'evoluzione delle tracce di usura dopo 100, 150, 300 e 800 cicli, mentre la FIGURA 3 riassume il tasso di usura medio dei diversi campioni nelle varie fasi del processo di usura.</p><p> </p><p style="text-align: justify;">Rispetto a un valore di COF di ~0,07 per gli altri tre campioni, il campione A presenta un COF molto più elevato, pari a ~0,15 all'inizio, che aumenta gradualmente e si stabilizza a ~0,3 dopo 300 cicli di usura. Un COF così elevato accelera il processo di usura e crea una quantità sostanziale di detriti di vernice, come indicato in FIGURA 4 - il topcoat del campione A ha iniziato a essere rimosso nei primi 100 giri. Come mostrato in FIGURA 3, il campione A presenta il tasso di usura più elevato, pari a ~5 μm2/N nei primi 300 cicli, che diminuisce leggermente a ~3,5 μm2/N a causa della migliore resistenza all'usura del substrato metallico. Il topcoat del campione C inizia a cedere dopo 150 cicli di usura, come mostrato in FIG. 4, che è anche indicato dall'aumento di COF in FIG. 2.</p><p> </p><p style="text-align: justify;">In confronto, il campione B e il campione D mostrano proprietà tribologiche migliori. Il campione B mantiene un basso COF per tutta la durata del test - il COF aumenta leggermente da~0,05 a ~0,1. Questo effetto lubrificante aumenta sostanzialmente la sua resistenza all'usura: il topcoat fornisce ancora una protezione superiore al primer sottostante dopo 800 cicli di usura. Il tasso di usura medio più basso, pari a soli ~0,77 μm2/N, è stato misurato per il campione B a 800 cicli. Lo strato superiore del campione D inizia a delaminare dopo 375 cicli, come dimostra il brusco aumento del COF in FIG. 2. Il tasso di usura medio del campione D è di circa 0,77 μm2/N. Il tasso di usura medio del campione D è di ~1,1 μm2/N a 800 cicli.</p><p> </p><p style="text-align: justify;">Rispetto alle tradizionali misure di abrasione Taber, il Tribometro NANOVEA fornisce valutazioni dell'usura ben controllate, quantificabili e affidabili, che garantiscono valutazioni riproducibili e controlli di qualità delle vernici commerciali per pavimenti/auto. Inoltre, la capacità di misurare il COF in situ consente agli utenti di correlare le diverse fasi di un processo di usura con l'evoluzione del COF, che è fondamentale per migliorare la comprensione fondamentale del meccanismo di usura e delle caratteristiche tribologiche di vari rivestimenti di vernice.</p>								</div>

									<p style="text-align: justify;">Le FIGURE 6 e 7 mostrano i graffi completi di tutti e quattro i campioni di vernice testati con un carico massimo di 5 N e 35 N, rispettivamente. Il campione D ha richiesto un carico maggiore di 50 N per delaminare il primer. Le prove di graffiatura a 5 N di carico finale (FIG. 6) valutano il cedimento coesivo/adesivo della vernice superiore, mentre quelle a 35 N (FIG. 7) valutano la delaminazione del primer. Le frecce nelle micrografie indicano il punto in cui il rivestimento superiore o il primer iniziano a essere completamente rimossi dal primer o dal substrato. Il carico in questo punto, il cosiddetto Carico Critico (Lc), viene utilizzato per confrontare le proprietà coesive o adesive della vernice, come riassunto nella Tabella 1.</p><p style="text-align: justify;"> </p><p style="text-align: justify;">È evidente che il campione di vernice D ha la migliore adesione interfacciale - mostrando i più alti valori di Lc di 4,04 N alla delaminazione della vernice e di 36,61 N alla delaminazione del primer. Il campione B mostra la seconda migliore resistenza ai graffi. L'analisi dei graffi dimostra che l'ottimizzazione della formula della vernice è fondamentale per il comportamento meccanico, o più specificamente, per la resistenza ai graffi e l'adesione delle vernici acriliche per pavimenti.</p>								</div>

									<p style="text-align: justify;">Rispetto alle tradizionali misure di abrasione Taber, il tester meccanico e il tribometro NANOVEA sono strumenti superiori per la valutazione e il controllo di qualità dei rivestimenti commerciali per pavimenti e per autoveicoli. Il NANOVEA Mechanical Tester in modalità Scratch può rilevare problemi di adesione/coesione in un sistema di rivestimento. Il Tribometro NANOVEA fornisce un'analisi tribologica ben controllata, quantificabile e ripetibile sulla resistenza all'usura e sul coefficiente di attrito delle vernici.</p><p> </p><p>Sulla base delle analisi tribologiche e meccaniche complete sui rivestimenti acrilici per pavimenti a base d'acqua testati in questo studio, dimostriamo che il campione B possiede il COF e il tasso di usura più bassi e la seconda migliore resistenza ai graffi, mentre il campione D mostra la migliore resistenza ai graffi e la seconda migliore resistenza all'usura. Questa valutazione ci permette di valutare e selezionare il miglior candidato in base alle esigenze dei diversi ambienti di applicazione.</p><p> </p><p>I moduli Nano e Micro del tester meccanico NANOVEA includono tutti modalità di indentazione, graffio e usura conformi alle norme ISO e ASTM, fornendo la più ampia gamma di test disponibili per la valutazione delle vernici su un unico modulo. Il tribometro NANOVEA offre test di usura e attrito precisi e ripetibili utilizzando modalità rotative e lineari conformi alle norme ISO e ASTM, con moduli opzionali per l'usura ad alta temperatura, la lubrificazione e la tribocorrosione disponibili in un unico sistema pre-integrato. La gamma impareggiabile di NANOVEA è la soluzione ideale per determinare l'intera gamma di proprietà meccaniche/tribologiche di rivestimenti, film e substrati sottili o spessi, morbidi o duri, tra cui durezza, modulo di Young, tenacità alla frattura, adesione, resistenza all'usura e molte altre. Sono disponibili profilatori ottici senza contatto NANOVEA opzionali per l'acquisizione di immagini 3D ad alta risoluzione di graffi e tracce di usura, oltre ad altre misure di superficie come la rugosità.</p>								</div>

									<p>La frattografia è lo studio delle caratteristiche sulle superfici fratturate ed è stata storicamente studiata tramite microscopio o SEM. A seconda delle dimensioni dell&#039;elemento, per l&#039;analisi della superficie viene selezionato un microscopio (macro caratteristiche) o un SEM (nano e micro caratteristiche). Entrambi consentono in definitiva di identificare il tipo di meccanismo di frattura. Sebbene efficace, il microscopio presenta chiari limiti e il SEM nella maggior parte dei casi, oltre all’analisi a livello atomico, non è pratico per la misurazione della superficie della frattura e manca di una più ampia capacità di utilizzo. Con i progressi nella tecnologia di misurazione ottica, NANOVEA <a href="https://nanovea.com/profilometers/">Profilometro 3D senza contatto</a> è ora considerato lo strumento preferito, con la sua capacità di fornire misurazioni di superfici 2D e 3D su scala nanometrica e macrometrica</p>								</div>

									<p>A differenza di un SEM, un profilometro 3D senza contatto può misurare quasi tutte le superfici, le dimensioni del campione, con una preparazione minima del campione, il tutto offrendo dimensioni verticali e orizzontali superiori a quelle di un SEM. Con un profilatore, le caratteristiche da nano a macro gamma sono catturate in una singola misurazione con zero influenza dalla riflettività del campione. Misura facilmente qualsiasi materiale: trasparente, opaco, speculare, diffusivo, lucido, ruvido, ecc. Il profilometro 3D senza contatto fornisce una capacità ampia e facile da usare per massimizzare gli studi sulla frattura della superficie ad una frazione del costo di un SEM.</p>								</div>

									<p>In questa applicazione, abbiamo mostrato come il NANOVEA ST400 3D Non-Contact Profilometer può caratterizzare con precisione la topografia completa (nano, micro e macro caratteristiche) di una superficie fratturata. Dall'area 3D, la superficie può essere chiaramente identificata e le sottoaree o i profili/sezioni trasversali possono essere rapidamente estratti e analizzati con una lista infinita di calcoli della superficie. Le caratteristiche superficiali sub nanometriche possono essere ulteriormente analizzate con un modulo AFM integrato.</p><p>Inoltre, NANOVEA ha incluso una versione portatile alla sua linea di profilometri, particolarmente importante per gli studi sul campo dove la superficie di frattura è immobile. Con questo ampio elenco di capacità di misurazione della superficie, l'analisi della superficie di frattura non è mai stata così facile e conveniente con un unico strumento.</p>								</div>

									Sebbene gli usi del rinforzo in fibra di vetro siano molteplici, nella maggior parte delle applicazioni è fondamentale che siano il più resistenti possibile. I compositi in fibra di vetro hanno uno dei più alti rapporti tra resistenza e peso disponibili e in alcuni casi, libbra per libbra, sono più resistenti dell'acciaio. Oltre all'elevata resistenza, è importante che la superficie esposta sia la più ridotta possibile. Ampie superfici in vetroresina possono rendere la struttura più vulnerabile agli attacchi chimici ed eventualmente all'espansione del materiale. Pertanto, l'ispezione delle superfici è fondamentale per il controllo della qualità della produzione.								</div>

									<p>Come mostrato nei risultati, il NANOVEA ST400 Optical <a href="https://nanovea.com/profilometers/">Profilatore</a> è stato in grado di misurare con precisione la rugosità e la planarità della superficie composita in fibra di vetro. I dati possono essere misurati su più lotti di compositi in fibra e/o un determinato periodo di tempo per fornire informazioni cruciali sui diversi processi di produzione della fibra di vetro e su come reagiscono nel tempo. Pertanto, l’ST400 è una valida opzione per rafforzare il processo di controllo qualità dei materiali compositi in fibra di vetro.</p>								</div>
