Wear-Resistant Coating on Hard Alloy

Abstract

In this research new data on the effect of zirconium as an ingredient of the ionic-plasma (Ti, Zr)N coating which is spread on the alloy VK10 KS was obtained. It was found that the introduction of zirconium into the coating composition led to an increase in nanohardness by 23 % up to 38500 MPa and in Young’s modulus – by 67 %, which indicated an increase of energy of atomic bonds and in strength of materials. Also, it led to an increase in an antifriction ability and decrease in the friction constant of the coating up to μ = 0,07, a satisfactory adhesive strength of coating, i.e. in general improved the service features of the whole alloy.
