文摘

TiSiC-Cr coatings were deposited via cathodic arc evaporation. The coatings derived from C2H2 outperformed those prepared in CH4 plasma. The coatings consisted of a mixture of crystalline solid solution carbide and amorphous hydrogenated carbon phases. The coatings produced with C2H2 exhibited the highest hardness, the lowest friction coefficient and wear resistance.
