Materials Science Aims and scope

Abstract

The electric-spark alloying of 45 steel with electrodes made of WC + Co + (2–4)% Cr3C2 hard alloys obtained by sintering on the “coating-substrate” boundary leads to the formation of an intermediate zone. This zone is formed as a result of cavitation mixing of the materials of the electrodes in the course of spark discharge and its composition corresponds to the composition of high-alloy high-speed steel. The intermediate zone increases the cohesion strength between the coating and the substrate, the depth of the obtained layer, and its wear resistance.
