Fracture Resistance Enhancement in Hard Mo-B-C Coatings Tailored by Composition and Microstructure

Figure 1

Residual imprints after indentation tests made into identically thick coatings of (a) TiN, (b) Al28Ti20N52, (c) TiB2, and (d) Cu. TiN, Al28Ti20N52, and TiB2 coatings were indented with the load of 1 N; the more softer copper coating was indented with much lower load to obtain similar indentation depth as in the hard TiN, Al28Ti20N52, and TiB2 coatings.
