【 摘 要 】

The regularities of wear and fracture of 40Cr steel, titanium and hard alloy specimens with hard coatings obtained by plasma-assisted sputtering arc were investigated. It is shown that ion-plasma coating deposition depends on the parameters of the coating deposition process, preliminary hardening of the substrate material and the composition of the cathodes for electric arc evaporator. Friction tests revealed a fundamentally different wear character of coatings obtained without and under negative offset voltage on the substrate. The kinetics of wear of coatings was investigated by the methods of acoustic emission and X-ray analysis.
