Abstract

In the present study, copper matrix composite samples with 53 volume percent WC reinforcement particles were produced using the infiltration technique. The density and electrical conductivity of the composite samples produced by this technique were measured. Moreover, the wear behavior of WC/Cu composite was investigated using the pin-on-disk method with an abrasive disk made up of SiC. It was found that the final density approaches the theoretical density with an increase in the temperature and time of the infiltration process, and for a given temperature, the density increases as the time increases. For an applied normal load of 9 N, the wear rate of WC/Cu composite increases linearly with the applied load. The presence of porosity increased the wear rate of the composite due to a decrease in the effective contact surface and induced notch effect on the composite surface.
