The interfacial roughness and the adhesion strength are very important for making a high-quality coating for friction and wear applications. In order to obtain a quantitative understanding concerning the effect of the two factors on the local delamination of hard coatings, finite element analyses concerning the maximum shear stress in a hard coating with various kinds of interfacial roughness and adhesion strength were made under low and high frictional conditions. As a result, local delamination maps for the identification of the local delamination of hard coatings were obtained as a function of the shear strength ratio of coating to substrate and the ratio of coating thickness to half-contact width. Also, the critical contact pressure required to produce local delamination of hard coatings is given.
