Abstract

Comparative studies of the fracture behavior and adhesion strength during scratch testing of a wear-resistant ion-plasma vacuum-arc Ti–N, Ti–Al–N, Ti–Al–Cr–N, and Ti–Al–Ni–N coatings are carried out by the scratch test. The type of failure and the adhesion strength characteristics of the coatings based on L_C1, L_C2, and L_C3 are determined by their structure, by the H³/E ² and H/E parameter values, and by the values of compressive macrostresses.
