									<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>

It acquires data points from deep crevices and complex geometries without introducing measurement errors or artifacts caused by local plastic deformation and without requiring extensive data manipulation.</p><p data-start="715" data-end="1135">Compared to focus variation systems, single-point optical sensing provides superior lateral and height accuracy, with X/Y resolution below 0.5 µm, maximum vertical resolution of 1.9 nm, and the ability to measure surface angles up to 87°.

									<p>El shot peening es un proceso en el que un sustrato se bombardea con perlas esféricas de metal, vidrio o cerámica -comúnmente denominadas "granalla"- a una fuerza destinada a inducir plasticidad en la superficie.

									<p>A diferencia de los perfilómetros de contacto tradicionales, que se han utilizado tradicionalmente para el análisis de superficies granalladas, la medición 3D sin contacto proporciona una imagen 3D completa para ofrecer una comprensión más exhaustiva del área de cobertura y la topografía de la superficie. Sin capacidades 3D, una inspección se basará únicamente en información 2D, que es insuficiente para caracterizar una superficie. Comprender la topografía, el área de cobertura y la rugosidad en 3D es el mejor enfoque para controlar o mejorar el proceso de peening. NANOVEA <a href="https://nanovea.com/profilometers/">Perfilómetros 3D sin contacto</a> utilizan la tecnología de luz cromática con una capacidad única para medir ángulos pronunciados que se encuentran en superficies mecanizadas y granalladas. Además, cuando otras técnicas no proporcionan datos fiables debido al contacto de la sonda, la variación de la superficie, el ángulo o la reflectividad, los perfilómetros NANOVEA lo consiguen.</p>								</div>

Es evidente que tanto la superficie 1 como la superficie 2 tienen un impacto significativo en todos los parámetros reportados aquí en comparación con el material en bruto. Un simple examen visual de las imágenes revela las diferencias entre las superficies. Esto se confirma observando el área de cobertura y los parámetros enumerados. En comparación con la superficie 2, la superficie 1 presenta una rugosidad media inferior (Sa), abolladuras menos profundas (Sv) y un área de superficie reducida (Sdar), pero un área de cobertura ligeramente superior.</p><p>A partir de estas mediciones de superficie en 3D, las áreas de interés pueden identificarse fácilmente y someterse a una amplia gama de mediciones, como Rugosidad, Acabado, Textura, Forma, Topografía, Planitud, Alabeo, Planaridad, Volumen, Paso-Altura y otras. Se puede elegir rápidamente una sección transversal 2D para realizar un análisis detallado. Esta información permite una investigación exhaustiva de las superficies granalladas, utilizando una gama completa de recursos de medición de superficies. Las áreas específicas de interés pueden examinarse más a fondo con un módulo AFM integrado. Los perfilómetros NANOVEA 3D ofrecen velocidades de hasta 200 mm/s. Se pueden personalizar en términos de tamaño, velocidades, capacidades de escaneado e incluso pueden cumplir las normas de Sala Limpia de Clase 1. También están disponibles opciones como el transportador de indexación y la integración para uso en línea o en línea.</p></div></div></div></div></div></div>								</div>

									<p>La pintura suele aplicarse en forma líquida y se somete a un proceso de secado, que implica la evaporación de disolventes y la transformación de la pintura líquida en una película sólida. Durante el proceso de secado, la superficie de la pintura cambia progresivamente de forma y textura. Se pueden conseguir diferentes acabados y texturas superficiales utilizando aditivos para modificar la tensión superficial y las propiedades de fluidez de la pintura. Sin embargo, en los casos de una receta de pintura mal formulada o un tratamiento superficial inadecuado, pueden producirse fallos no deseados en la superficie de la pintura.</p>
<p>La monitorización precisa in situ de la morfología de la superficie de la pintura durante el periodo de secado puede proporcionar información directa sobre el mecanismo de secado. Además, la evolución en tiempo real de las morfologías superficiales es una información muy útil en diversas aplicaciones, como la impresión 3D.

									<p>La pintura se aplicó sobre la superficie de una chapa metálica, seguida inmediatamente de mediciones automatizadas de la evolución de la morfología de la pintura en secado in situ utilizando el perfilómetro sin contacto NANOVEA ST500 equipado con un sensor de línea de alta velocidad. Se había programado una macro para medir y registrar automáticamente la morfología 3D de la superficie a intervalos de tiempo específicos: 0, 5, 10, 20, 30, 40, 50 y 60 min. Este procedimiento de escaneado automatizado permite a los usuarios realizar tareas de escaneado automáticamente ejecutando procedimientos establecidos en secuencia, lo que reduce significativamente el esfuerzo, el tiempo y los posibles errores del usuario en comparación con las pruebas manuales o los escaneados repetidos. Esta automatización resulta extremadamente útil para mediciones a largo plazo que implican múltiples exploraciones a diferentes intervalos de tiempo.</p><p>El sensor óptico de línea genera una línea brillante formada por 192 puntos, como se muestra en la FIGURA 1. Estos 192 puntos luminosos escanean simultáneamente la superficie de la muestra, lo que aumenta significativamente la velocidad de escaneado. Esto garantiza que cada escaneado 3D se complete rápidamente para evitar cambios sustanciales en la superficie durante cada escaneado individual.</p>								</div>

									<p>La vista en falso color, la vista en 3D y el perfil en 2D de la topografía de la pintura secándose en momentos representativos se muestran en la FIGURA 2, FIGURA 3 y FIGURA 4, respectivamente. El falso color en las imágenes facilita la detección de características que no son fácilmente discernibles. Los diferentes colores representan variaciones de altura en diferentes áreas de la superficie de la muestra. La vista 3D proporciona una herramienta ideal para que los usuarios observen la superficie de la pintura desde diferentes ángulos. Durante los primeros 30 minutos de la prueba, los falsos colores de la superficie de la pintura cambian gradualmente de tonos más cálidos a tonos más fríos, lo que indica una disminución progresiva de la altura con el paso del tiempo en este periodo. Este proceso se ralentiza, como demuestra el leve cambio de color al comparar la pintura a los 30 y 60 minutos.</p><p>Los valores de la altura media de la muestra y de la rugosidad Sa en función del tiempo de secado de la pintura se representan en la FIGURA 5. El análisis completo de la rugosidad de la pintura después de 0, 30 y 60 min de tiempo de secado se enumeran en la TABLA 1. Puede observarse que la altura media de la superficie de la pintura disminuye rápidamente de 471 a 329 µm en los primeros 30 min de tiempo de secado. La textura de la superficie se desarrolla al mismo tiempo que se vaporiza el disolvente, lo que provoca un aumento del valor Sa de la rugosidad de 7,19 a 22,6 µm. El proceso de secado de la pintura se ralentiza a partir de entonces, lo que provoca una disminución gradual de la altura de la muestra y del valor Sa hasta 317 µm y 19,6 µm, respectivamente, a los 60 min.</p><p>Este estudio pone de relieve las capacidades del perfilómetro 3D sin contacto NANOVEA para monitorizar en tiempo real los cambios de la superficie 3D de la pintura en proceso de secado, proporcionando información valiosa sobre el proceso de secado de la pintura. Al medir la morfología de la superficie sin tocar la muestra, el perfilómetro evita introducir alteraciones de forma en la pintura sin secar, lo que puede ocurrir con tecnologías de contacto como el palpador deslizante. Este enfoque sin contacto garantiza un análisis preciso y fiable de la morfología de la superficie de la pintura en proceso de secado.</p>								</div>

<p>En esta aplicación, hemos mostrado las capacidades del perfilómetro 3D sin contacto NANOVEA ST500 para supervisar la evolución de la morfología de la superficie de la pintura durante el proceso de secado. El sensor óptico de línea de alta velocidad, que genera una línea con 192 puntos de luz que escanean la superficie de la muestra simultáneamente, ha hecho que el estudio sea eficiente en cuanto al tiempo, al tiempo que garantiza una precisión inigualable.</p>
<p>La función macro del software de adquisición permite programar mediciones automatizadas de la morfología de la superficie 3D in situ, por lo que resulta especialmente útil para mediciones a largo plazo que impliquen múltiples exploraciones a intervalos de tiempo específicos. Reduce significativamente el tiempo, el esfuerzo y los posibles errores del usuario. Los cambios progresivos en la morfología de la superficie se supervisan continuamente y se registran en tiempo real a medida que se seca la pintura, lo que proporciona información valiosa sobre el mecanismo de secado de la pintura.</p>
<p>Los datos mostrados aquí representan sólo una fracción de los cálculos disponibles en el software de análisis. Los perfilómetros NANOVEA son capaces de medir prácticamente cualquier superficie, ya sea transparente, oscura, reflectante u opaca.</p></div></div></div>

									<p>La fractografía es el estudio de las características de las superficies fracturadas y, históricamente, se ha investigado mediante microscopio o SEM. Dependiendo del tamaño de la característica, se selecciona un microscopio (características macro) o un SEM (características nano y micro) para el análisis de la superficie. Ambos permiten, en última instancia, identificar el tipo de mecanismo de fractura. Aunque eficaz, el microscopio tiene claras limitaciones y, en la mayoría de los casos, salvo para el análisis a nivel atómico, el SEM no es práctico para la medición de superficies fracturadas y carece de una capacidad de uso más amplia. Con los avances en la tecnología de medición óptica, el NANOVEA <a href="https://nanovea.com/profilometers/">Perfilómetro 3D sin contacto</a> Ahora se considera el instrumento preferido, gracias a su capacidad para proporcionar mediciones de superficies en 2D y 3D a escala nano y macro.</p>								</div>

									<p>A diferencia de un SEM, un perfilómetro 3D sin contacto puede medir casi cualquier superficie y tamaño de muestra, con una preparación mínima de la muestra, al tiempo que ofrece dimensiones verticales/horizontales superiores a las de un SEM. Con un perfilómetro, las características del rango nano a macro se capturan en una sola medición sin influencia alguna de la reflectividad de la muestra. Mida fácilmente cualquier material: transparente, opaco, especular, difusivo, pulido, rugoso, etc. El perfilómetro 3D sin contacto ofrece una amplia capacidad y es fácil de usar para maximizar los estudios de fractura de superficies a una fracción del costo de un SEM.</p>								</div>

									<p>En esta aplicación, hemos mostrado cómo el perfilómetro 3D sin contacto NANOVEA ST400 puede caracterizar con precisión la topografía completa (características nano, micro y macro) de una superficie fracturada. A partir del área 3D, la superficie se puede identificar claramente y se pueden extraer y analizar rápidamente subáreas o perfiles/secciones transversales con una lista interminable de cálculos de superficie. Las características de la superficie subnanométricas se pueden analizar más a fondo con un módulo AFM integrado.</p><p>Además, NANOVEA ha incluido una versión portátil en su línea de perfilómetros, especialmente importante para estudios de campo en los que la superficie de fractura es inamovible. Con esta amplia lista de capacidades de medición de superficies, el análisis de superficies de fractura nunca ha sido tan fácil y cómodo con un solo instrumento.</p>								</div>

									Aunque hay muchos usos para el refuerzo de fibra de vidrio, en la mayoría de las aplicaciones es crucial que sean lo más resistentes posible. Los compuestos de fibra de vidrio tienen una de las relaciones resistencia-peso más altas que existen y, en algunos casos, son más resistentes que el acero. Además de su alta resistencia, también es importante que la superficie expuesta sea lo más pequeña posible. Las superficies grandes de fibra de vidrio pueden hacer que la estructura sea más vulnerable a los ataques químicos y, posiblemente, a la expansión del material. Por lo tanto, la inspección de la superficie es fundamental para el control de calidad de la producción.								</div>

									<p>La fricción y el desgaste son inevitables en las correas de una máquina accionada por correa. Una fricción suficiente garantiza una transmisión eficaz de la potencia sin deslizamientos, pero una fricción excesiva puede desgastar rápidamente la correa. Durante el funcionamiento de la transmisión por correa se producen diferentes tipos de desgaste, como la fatiga, la abrasión y la fricción. Con el fin de prolongar la vida útil de la correa y reducir los costes y el tiempo de reparación y sustitución de la correa, es conveniente evaluar de forma fiable el desgaste de las correas para mejorar su vida útil, la eficacia de la producción y el rendimiento de la aplicación. La medición precisa del coeficiente de fricción y del índice de desgaste de la correa facilita la I+D y el control de calidad de la producción de correas.</p>								</div>

									<p><span class="fontstyle0">FIGURA 1 </span><span class="fontstyle2">muestra la evolución del COF de las correas durante las pruebas de desgaste. Las correas con diferentes texturas muestran comportamientos de desgaste sustancialmente diferentes. Resulta interesante que, tras el periodo de rodaje durante el cual el COF aumenta progresivamente, la correa texturizada alcanza un COF inferior de ~0,5 en las dos pruebas realizadas con cargas de 10 N y 100 N. En comparación, la correa lisa sometida a la carga de 10 N muestra un COF significativamente superior de~ 1,4 cuando el COF se estabiliza y se mantiene por encima de este valor durante el resto de la prueba. La correa lisa sometida a la carga de 100 N se desgastó rápidamente por la bola de acero 440 y formó una gran huella de desgaste. Por lo tanto, la prueba se detuvo a 220 revoluciones.</span></p>								</div>

									<p class="MsoNormal">El perfil 3D de la huella de desgaste permite determinar de forma directa y precisa el volumen de la huella de desgaste calculado por el software de análisis avanzado, como se muestra en la TABLA 1. En una prueba de desgaste de 220 revoluciones, la correa lisa presenta una huella de desgaste mucho mayor y más profunda, con un volumen de 75,7 mm3, en comparación con un volumen de desgaste de 14,0 mm3 para la correa texturada tras una prueba de desgaste de 600 revoluciones. La fricción significativamente mayor de la correa lisa contra la bola de acero da lugar a un índice de desgaste 15 veces superior al de la correa texturada.</p><p class="MsoNormal"> </p><p class="MsoNormal">Una diferencia tan drástica de COF entre la banda texturizada y la banda lisa está posiblemente relacionada con el tamaño del área de contacto entre la banda y la bola de acero, lo que también conduce a su diferente rendimiento frente al desgaste. La FIGURA 3 muestra las huellas de desgaste de las dos correas bajo el microscopio óptico. El examen de las huellas de desgaste concuerda con la observación de la evolución del COF: La correa texturizada, que mantiene un COF bajo de ~0,5, no muestra ningún signo de desgaste después de la prueba de desgaste con una carga de 10 N. La correa lisa muestra una pequeña huella de desgaste a 10 N. Las pruebas de desgaste realizadas a 100 N crean huellas de desgaste sustancialmente mayores tanto en la correa texturizada como en la lisa, y la tasa de desgaste se calculará utilizando perfiles 3D, como se verá en el párrafo siguiente.</p>								</div>

									<p>En este estudio, mostramos la capacidad del Tribómetro NANOVEA T2000 para evaluar el coeficiente de fricción y la tasa de desgaste de las correas de una manera bien controlada y cuantitativa. La textura de la superficie desempeña un papel crítico en la resistencia a la fricción y al desgaste de las correas durante su funcionamiento en servicio. La correa texturizada presenta un coeficiente de fricción estable de ~0,5 y posee una larga vida útil, lo que se traduce en una reducción del tiempo y los costes de reparación o sustitución de las herramientas. En comparación, la excesiva fricción de la correa lisa contra la bola de acero desgasta rápidamente la correa. Además, la carga sobre la correa es un factor vital de su vida útil. La sobrecarga crea una fricción muy elevada, lo que acelera el desgaste de la correa.</p>
<p>El tribómetro NANOVEA T2000 ofrece pruebas de desgaste y fricción precisas y repetibles utilizando modos rotativos y lineales conformes a ISO y ASTM, con módulos opcionales de desgaste a alta temperatura, lubricación y tribocorrosión disponibles en un sistema preintegrado.&nbsp;<span style="font-size: 16.8px;">NANOVEA&nbsp;</span>es una solución ideal para determinar toda la gama de propiedades tribológicas de revestimientos, películas y sustratos finos o gruesos, blandos o duros.</p>								</div>

									<p>Los fósiles son restos conservados de plantas, animales y otros organismos enterrados en sedimentos bajo antiguos mares, lagos y ríos. Los tejidos blandos del cuerpo suelen descomponerse tras la muerte, pero las conchas duras, los huesos y los dientes se fosilizan. Las características de la microestructura de la superficie suelen conservarse cuando se produce la sustitución mineral de las conchas y los huesos originales, lo que permite conocer la evolución del clima y el mecanismo de formación de los fósiles.</p>								</div>

									<p>Los perfiles 3D del fósil nos permiten observar las características detalladas de la superficie de la muestra fósil desde un ángulo más cercano. Es posible que la alta resolución y precisión del perfilómetro NANOVEA no sean perceptibles a simple vista. El software de análisis del perfilómetro ofrece una amplia gama de estudios aplicables a estas superficies únicas. A diferencia de otras técnicas, como las sondas táctiles, el NANOVEA <a href="https://nanovea.com/profilometers/">Perfilómetro 3D sin contacto</a> mide las características de la superficie sin tocar la muestra. Esto permite conservar las características reales de la superficie de ciertas muestras fósiles delicadas. Además, el perfilómetro portátil Jr25 permite realizar mediciones en 3D en yacimientos fósiles, lo que facilita considerablemente el análisis y la protección de los fósiles tras la excavación.</p>								</div>

									<p><span style="font-size: 16.8px;">En esta aplicación, hemos estudiado exhaustivamente las características de la superficie 3D de un fósil de braquiópodo y crinoideo utilizando el perfilómetro portátil sin contacto NANOVEA Jr25. Demostramos que el instrumento puede caracterizar con precisión la morfología 3D de las muestras fósiles. A continuación, se analizan con mayor detalle las interesantes características y texturas de la superficie de las muestras. La muestra de braquiópodo posee una textura de surcos divergentes, mientras que el fósil de tallo de crinoide muestra una textura isotrópica preferencial. Los escaneos tridimensionales detallados y precisos de la superficie resultan ser herramientas ideales para que los paleontólogos y geólogos estudien la evolución de la vida y la formación de los fósiles.</span></p><p><span style="color: var( --e-global-color-text ); background-color: rgba(255, 255, 255, 0);">Los datos que se muestran aquí representan solo una parte de los cálculos disponibles en el software de análisis.

									<p>En esta aplicación, hemos mostrado cómo el perfilómetro 3D NANOVEA ST400 puede caracterizar con precisión el acabado superficial del cuero procesado. En este estudio, la capacidad de medir la rugosidad superficial, la profundidad, el paso y el diámetro de las hendiduras nos permitió cuantificar las diferencias entre el acabado y la calidad de las dos muestras, que podrían no ser evidentes a simple vista.</p><p>En general, no se observaron diferencias visibles en el aspecto de los escaneos 3D entre la MUESTRA 1 y la MUESTRA 2. Sin embargo, en el análisis estadístico se aprecia una clara distinción entre ambas muestras. La MUESTRA 1 contiene una mayor cantidad de hoyuelos con diámetros más pequeños, mayor profundidad y menor distancia entre hoyuelos en comparación con la MUESTRA 2.</p><p>Tenga en cuenta que hay estudios adicionales disponibles. Se podrían haber analizado más a fondo áreas de interés especiales con un módulo AFM o microscopio integrado. El perfilómetro 3D NANOVEA alcanza velocidades de entre 20 mm/s y 1 m/s para laboratorio o investigación, con el fin de satisfacer las necesidades de inspección a alta velocidad; se puede fabricar con tamaños, velocidades y capacidades de escaneo personalizados, cumplimiento de la norma de sala limpia de clase 1, cinta transportadora de indexación o para integración en línea o en línea.</p>								</div>

La comprensión de las estructuras superficiales que se encuentran en la naturaleza ha dado lugar a estudios de adhesión basados en las patas del gecko, estudios de resistencia basados en el cambio de textura de los pepinos de mar y estudios de repelencia basados en las hojas, entre muchos otros. Estas superficies tienen numerosas aplicaciones potenciales, desde la biomedicina hasta la confección y la automoción.

									<p style="text-align: justify;">Utilizando la tecnología Chromatic Light, el NANOVEA Jr25 Portable <a href="https://nanovea.com/profilometers/">Perfilador óptico</a> tiene una capacidad superior para medir casi cualquier material. Esto incluye los ángulos únicos y pronunciados, las superficies reflectantes y absorbentes que se encuentran en la amplia gama de características superficiales de la naturaleza. Las mediciones 3D sin contacto proporcionan una imagen 3D completa que permite comprender mejor las características de la superficie. Sin las capacidades 3D, la identificación de las superficies naturales se basaría únicamente en información 2D o en imágenes microscópicas, lo que no proporciona información suficiente para imitar adecuadamente la superficie estudiada. Comprender toda la gama de características de la superficie, incluyendo la textura, la forma y las dimensiones, entre muchas otras, será fundamental para el éxito de la fabricación.</p>
