MICROHARDNESS AND MICROSCRATCH TESTS

This technique can be used to study the mecanical properties of coatings such as hardness, adhesion or resistance to delamination. During the tests, an indentation (Vickers) or a scratch is made on the surface of the sample using a diamond or tungsten carbide stylus. Tribological measurements can also be performed by moving back and forth and measuring the charge needed to start deteriorating the sample (critical charge).
