The titanium diboride(TiB 2 ) has high strength(750MPa), high melting point (3225 ? C)and10% IACS electrical conductivity. On this account, the dispersion hardening Cu?TiB 2 composites(MMCs) are a promising candidate for applications as electrical contact materials. MMCs for electrical contact materials can reduce material cost and resource consumption caused by wear, due to its good mechanical and electrical property. In this study, we attempt to prepare MMCs with various volume fraction and particle size of TiB 2 by means of hot extruded and cold drawn process. Dry sliding wear tests were performed on a pin-on-disk type wear tester, sliding against SM45C under the different applied loads. After wear testing, the microstructures of the worn surfaces were observed by SEM and the microhardnesses of the subsurface zone were measured.

Keywords:wear;worn surface;subsurface zone
