Abstrakt: The four different contents of (Cu/50W)- TiC composites were prepared by spark plasma sintering method. The density, relative density, micro-hardness and conductivity were determined, respectively. The microstructure of the composite was analyzed by SEM. The wear resistance was investigated by a QG-700 atmosphere and high temperature friction and wear tester. The results show that, when the content of TiC is 3%, the optimum comprehensive properties of the (Cu/50W)-3TiC composite are obtained. The density, micuo-hardness and conductivity of the composites are 98.7%, 113HV10 and 61.4%IACS, respectively. The wear mechanisms of the (Cu/50W)- TiC composites are mainly of micro-cutting wear and adhesive wear.
