Adhesion Properties Evaluation of Heat Treated Steel 100Cr6 with Applied DLC Coating

Abstract

The article deals with determination of tribological and basic properties of heat-treated bearing steel 100Cr6. It is typical steel for production a small and medium size of rolling bearings. For reducing the friction coefficient of functional surfaces of heat-treated bearing steel 100Cr6, the application of DLC (Diamond Like Carbon) coating is used. The quality of the thin surface coating was evaluate in terms of adhesion-cohesive properties. The measurement of the mechanical properties nanohardness, modulus of elasticity was perform by the nanoindentation method. A scratch test was use for analysis of adhesion properties. All results of experimental measurements will suitable for design of carry materials and iron-based materials. The work was done by financial support of project No. KEGA 026ŽU-4/2019 Implementation of integrated GPS system for specification and products verification into the teaching process of engineering study programs and putting them into the technical practice at the University of Žilina, Department of Mechanical Design and Machine Elements.
