Abstract:

The experimental model permitting the detection of coating non-homogeneity is suggested for standard depth sensing indentation tests. It is assumed that the shear modulus varies arbitrarily with depth in a nanostructured coating. It is defined a notion of the stiffness as a function of radius of a contact zone for nanostructured coating coupled with homogeneous half-space, which makes it possible to classify the non-homogeneity of a coating. Using numerical examples, the influence of different laws of shear modulus variation in a coating on the stiffness is studied.
