Originally developed by a German mineralogist Friedrich Mohs in 1820, scratch hardness test determines the hardness of a material to scratches and abrasion due to friction from a sharp object1.

									<p>La durezza misura la resistenza dei materiali alla deformazione permanente o plastica. Originariamente sviluppato dal mineralogista tedesco Friedrich Mohs nel 1820, il test di durezza al graffio determina la durezza di un materiale ai graffi e all'abrasione dovuti all'attrito di un oggetto appuntito.<sup>1</sup>. La scala di Mohs è un indice comparativo piuttosto che una scala lineare, pertanto è stata sviluppata una misurazione della durezza da graffio più accurata e qualitativa, descritta nella norma ASTM G171-03.<sup>2</sup>. Misura la larghezza media del graffio creato da uno stilo di diamante e calcola il numero di durezza del graffio (HSP).</p>								</div>

									<p>I materiali vengono selezionati in base ai requisiti di servizio. Per le applicazioni che comportano variazioni significative di temperatura e gradienti termici, è fondamentale studiare le proprietà meccaniche dei materiali alle alte temperature per essere pienamente consapevoli dei limiti meccanici. I materiali, soprattutto i polimeri, di solito si ammorbidiscono alle alte temperature. Molti guasti meccanici sono causati da deformazioni per scorrimento e fatica termica che avvengono solo a temperature elevate. Pertanto, è necessario disporre di una tecnica affidabile per la misurazione della durezza alle alte temperature, al fine di garantire una corretta selezione dei materiali per le applicazioni ad alta temperatura.</p>								</div>

									<p style="text-align: left;">I profili delle tracce di graffio del campione di teflon a diverse temperature sono mostrati nella FIGURA 1, per confrontare la durezza del graffio a diverse temperature elevate. L'accumulo di materiale sui bordi della traccia di graffio si forma quando lo stilo viaggia con un carico costante di 2 N e colpisce il campione di Teflon, spingendo e deformando lateralmente il materiale nella traccia di graffio.</p><p>Le larghezze delle tracce di graffio misurate e i numeri di durezza di graffio calcolati (HSP) sono riassunti e confrontati nella FIGURA 3. L'ampiezza della traccia di graffio misurata al microscopio è in accordo con quella misurata con il profilatore NANOVEA - il campione di Teflon mostra un'ampiezza di graffio maggiore a temperature più elevate. La larghezza della traccia del graffio aumenta da 281 a 539 µm quando la temperatura passa da RT a 300oC, con una conseguente diminuzione dell'HSP da 65 a 18 MPa.</p><p>La durezza da graffio a temperature elevate può essere misurata con elevata precisione e ripetibilità utilizzando il tribometro NANOVEA T50. Questa soluzione rappresenta un'alternativa alle altre misure di durezza e rende i tribometri NANOVEA un sistema più completo per le valutazioni tribomeccaniche ad alta temperatura.</p>								</div>

									<p>In questo studio, mostriamo come il tribometro NANOVEA misura la durezza da graffio a temperature elevate, in conformità con la norma ASTM G171-03. Il test di durezza da graffio a carico costante fornisce una soluzione alternativa e semplice per confrontare la durezza dei materiali utilizzando il tribometro. La capacità di eseguire misure di durezza da graffio a temperature elevate rende il tribometro NANOVEA uno strumento ideale per valutare le proprietà tribomeccaniche ad alta temperatura dei materiali.</p><p>Il tribometro NANOVEA offre anche 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. È disponibile un profilatore 3D senza contatto opzionale per l'acquisizione di immagini 3D ad alta risoluzione delle tracce di usura, oltre ad altre misure di superficie come la rugosità.</p>								</div>

									Immaginate uno scenario in cui un campione sfuso viene riscaldato uniformemente a una velocità costante. Quando un materiale sfuso si riscalda e si avvicina al suo punto di fusione, inizia a perdere la sua rigidità. Se si eseguono indentazioni periodiche (prove di durezza) con la stessa forza target, la profondità di ciascuna indentazione dovrebbe aumentare costantemente, poiché il campione sta diventando più morbido (vedi figura 1). Ciò continua fino a quando il campione inizia a fondere. A questo punto, si osserverà un forte aumento della profondità di ciascuna tacca. Utilizzando questo concetto, il cambiamento di fase in un materiale può essere osservato utilizzando oscillazioni dinamiche con un'ampiezza di forza fissa e misurando il suo spostamento, ovvero l'analisi meccanica dinamica (DMA).

										<content:encoded><![CDATA[<p>ASTM D7187, la resistenza della vernice ai graffi e alle macchie gioca un ruolo fondamentale nel suo utilizzo finale. La vernice per autoveicoli soggetta a graffi rende difficile e costosa la manutenzione e la riparazione. Per ottenere la migliore resistenza ai graffi e alle macchie sono state sviluppate diverse architetture di rivestimento: primer, base e trasparente. <a href="https://nanovea.com/nano-scratch-tester/">Test di nanoscratch</a> è stato sviluppato come metodo di prova standard per misurare gli aspetti meccanici del comportamento al graffio/marmo dei rivestimenti vernicianti, come descritto nella norma ASTM D7187.<a href="#_edn1" name="_ednref1"></a>. Durante il test di graffiatura si verificano diversi meccanismi di deformazione elementare, ovvero deformazione elastica, deformazione plastica e frattura, a diversi carichi. Il test fornisce una valutazione quantitativa della resistenza plastica e della resistenza alla frattura dei rivestimenti vernicianti.</p>

										<content:encoded><![CDATA[<p>I materiali vengono selezionati in base ai requisiti di servizio. Per le applicazioni che comportano variazioni significative di temperatura e gradienti termici, è fondamentale studiare le proprietà meccaniche dei materiali alle alte temperature per essere pienamente consapevoli dei limiti meccanici. I materiali, soprattutto i polimeri, di solito si ammorbidiscono alle alte temperature. Molti guasti meccanici sono causati da deformazioni per scorrimento e fatica termica che avvengono solo a temperature elevate. Per questo motivo, è necessario disporre di una tecnica affidabile per misurare la durezza da graffio ad alta temperatura, al fine di garantire una corretta selezione dei materiali per le applicazioni ad alta temperatura.</p>
