La carga cr\u00edtica, a la que se produce un determinado tipo de fallo en el recubrimiento a medida que aumenta progresivamente la carga aplicada, se considera una herramienta fiable para determinar y comparar las propiedades adhesivas y cohesivas de los recubrimientos. El indentador m\u00e1s utilizado para las pruebas de rayado es el indentador c\u00f3nico de diamante Rockwell. Sin embargo, cuando la prueba de rayado se realiza sobre un recubrimiento polim\u00e9rico blando depositado sobre un sustrato fr\u00e1gil, como una oblea de silicio, el penetrador c\u00f3nico tiende a atravesar el recubrimiento formando surcos en lugar de crear grietas o delaminaci\u00f3n. La fractura de la oblea de silicio fr\u00e1gil se produce cuando la carga aumenta a\u00fan m\u00e1s. Por lo tanto, es fundamental desarrollar una nueva t\u00e9cnica para evaluar las propiedades de cohesi\u00f3n o adhesi\u00f3n de los recubrimientos blandos sobre un sustrato fr\u00e1gil.<\/p>\n<p><a href=\"https:\/\/nanovea.com\/App-Notes\/micro-scrape-test.pdf\">Prueba de microraspado de recubrimiento polim\u00e9rico<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Scratch testing has developed to be one of the most widely applied methods to evaluate the cohesive and adhesive strength of the coatings.
