Effect of titanium and tungsten carbide on the formation of the structure and properties of composite coatings. Part 3: wear resistance of steel R6M5–(WC+TiC)/TiC coatings

Abstract

The results of analysis of the relative abrasion wear resistance of composite coatings based on a high-speed tool steel are presented. It is shown that the R6M5 steel–(TiC+WC) coating, with the initial surfacing mixture containing 20% of the hardening phase (5% TiC+15% WC), has the highest wear resistance and does not require additional heat treatment.
