The tribotechnical characteristics of diamond-like coatings formed by hybrid technology

Abstract

The use of low temperatures to improve the performance of steel products is a widely used technology in mechanical engineering. Another direction of increasing the efficiency of machine parts and mechanisms is the creation of thin-layer systems using vacuum technologies. The combination of these technological approaches made it possible to obtain antifriction vacuum superhard coatings with increased tribotechnical characteristics. The effect of increasing the wear resistance of hybrid coatings is the formation of nanodisperse structures in the steel substrate and coating, the decay of residual austenite, which leads to an increase in martensite in the structure of steel subjected to cold treatment, a significant change in the values of internal stresses in superhard coatings.
