Impact Wear of Chromium Carbide Based Cermets

Abstract

Chromium carbide based cermets are perspective materials to use in aggressive and abrasive conditions. Present paper considers the impact wear properties of chromium carbide based cermets with different chemical compositions (10 wt % – 50 wt % of Ni). The investigated chromium carbide based cermets were produced by a novel method reactive sintering and reference materials using chromium carbide powders produced by indirect and direct synthesis. The impact wear resistance of chromium carbide based cermets depends on binder content and cermets producing technology. The wear resistance increases in increase of binder content. Better wear resistance exhibited cermets made by using chromium carbide powder produced by indirect synthesis. The wear mechanism was investigated by SEM images of worn surfaces of cermets.
