Wear mechanism of cemented carbide

Abstract

This paper describes wear mechanism of cemented carbide sliding against S45C steel. Following result was obtained by the sliding test. Wear volume was low to about 50m of sliding distance. 50m of sliding distance has low transferred volume and be hard to exfoliate. And, wear volume is proportional to transferred volume. From continuous SEM observation of WC particles on the wear scar, small particles are removed in the early stage of 50m and big particle is isolated. It is thought that wear volume increase with separation of big particles with transferred material.
