Abstract
The steel matrix composites with 5CrNiMo mold steel as substrate and WC particles as hard phase, were prepared by electroslag melting and casting. The composite material’s properties such as friction factor, wear volume and wear mechanism were investigated by scanning electron microscope (SEM) and friction wear test equipment. The results demonstrate that the sample’s abrasive resistance improved greatly after heat treatment. In the condition of dry sliding wear, surface peeling caused by adhesive wear and adrasive wear caused by wear debris as the third body are the main wear mechanism.
