Mechanical and Tribological Properties of PVD-Coated Cemented Carbide as Evaluated by a New Multipass Scratch-Testing Method
Figure 11
Coating failure map of the Ti0.34Al0.66N coating as obtained from the circular multi-pass scratch test. The map illustrates the influence of normalized normal load and number of cycles on dominant failure modes, that is, plastic deformation, cracking and wear, local spalling, and continuous spalling. In the map, four different regions, A, B, C, and D, are indicated.
