摘要

The 40-60 vol.%TiC_x-TiB₂/Cu composites were successfully fabricated by the combustion synthesis and hot press consolidation in a Cu-Ti-B₄C system. The final products consist of only Cu, TiC_x and TiB₂, and the ceramic particles distribute uniformly in the composites. The sizes of the ceramic particles decrease with the increasing Cu content. The yield strength, ultimate compression strength and microhardness increase with the increasing TiC_x-TiB₂ content. The incorporation of the TiC_x-TiB₂ particles improves the wear resistance of the composites effectively, and the wear resistance increase with the increase in the TiC_x-TiB₂ content.
