Abstract

Research into the influence of the carbon content in AlCrCN coatings on their phase composition and structure were carried out. A carbon solid solution was found to form in coatings when deposited by the cathodic-arc method in the acetylene gas atmosphere. The formation of the coatings having the B1-type phase structure and the [200] texture axis provided a level of their hardness at 3300 HK. The formation of a tribolayer consisting of oxides of the particles of both the coating and the counterbody was studied, leading to a friction coefficient of 0.6, without using a lubricant. The coating showed an almost twofold increase in adhesion to a Kh12MF die steel base material, and the carbon-containing coating showed an increase in crack resistance as compared to the AlCrN coating.
