Mechanical and Tribological Properties of PVD-Coated Cemented Carbide as Evaluated by a New Multipass Scratch-Testing Method
Figure 8
Cross-sections of the circular wear tracks illustrating (a) plastic deformation and minor cracking (no coating material detached), (b) continuous interfacial spalling (adhesive failure), and (c) interfacial cracking at the rim of a scratch track for Ti0.34Al0.66N coating. The arrows indicate the scratching direction.
