Mechanical and Tribological Properties of PVD-Coated Cemented Carbide as Evaluated by a New Multipass Scratch-Testing Method

Figure 9

Wear mechanisms observed in the multi-pass scratch test. (a) Chipping of fine coating fragments in connection to transverse cracking and (b) delamination of thin plate-like fragments (fractured cross section) originating from a thin tribo film for Ti0.34Al0.66N coating. The arrows indicate the scratching direction.
