AbstractThe influence has been studied of the crystallographic match of vacuum-arc deposited layers in anti-abrasive multi-layer films on their tribological properties. A three-layer coating (TiC⧹Ti(CxN1−x)⧹TiN) was selected as a model system and the effects examined of the crystallographic match of the constituent layers in the TiC–Ti(CxN1−x) and Ti(CxN1−x)–TiN interfaces on their sliding-wear-resistance. The sliding-wear characteristics were determined using the sliding friction of a steel ball on the surface of the selected sample followed by measurement of the volume of removed material. The sliding-wear-resistance was taken as the durability indicator-γ60. It was found that the sliding-wear intensity of the TiC⧹Ti(CxN1−x)⧹TiN multi-layer as a function of the composition of the working atmosphere for the Ti(CxN1−x) deposition changed in a nonlinear manner. The largest value of sliding-wear-resistance (durability indicator γ60 = 82×10[mm−3]) occurred for coating TiC⧹Ti(CxN1−x)⧹TiN, when the working atmosphere for the Ti(CxN1−x) layer was C2H2⧹N2 = 75\%⧹25\%. The minimum of the sliding-wear-resistance (durability indicator γ60 = 10×10[mm−3]) occurred when the working atmosphere for the Ti(CxN1−x) was C2H2⧹N2 = 50\%⧹50\%.
