SiC particulate reinforced copper (SiCp/Cu) matrix composites were fabricated by powder metallurgy, using SiCp of various grit sizes (a nominal diameter of 30㎚, 130㎚ and 14㎛, respectively) and micron Cu as the raw materials. The resulting composites specimens were hot extruded to get rid of the possible void and increase compactness. The friction and wear behaviors of various SiCp reinforced SiCp/Cu matrix composites sliding against a AISI5140 steel under the lubrication of 20<SUP>#</SUP> machinery oil were investigated on an MM-200 friction and wear tester in a block-on-ring configuration, using a pure copper fabricated by the above same manufacture method and a commercial bronze alloy (6.5-0.4 bronze) as a control. The microstructures and worn surface morphologies of the SiCp/Cu composites and the counterpart AISI5140 steel was observed on a scanning electron microscopy, while the elemental compositions on the worn surfaces of various SiCp/Cu matrix composites were determined by means of energy dispersive spectroscopy. As the results, the incorporation of the SiCp of various grit sizes contributed to increase the wear-resistance of the Cu-matrix materials considerably. The SiCp/Cu matrix composite reinforced with the SiCp of larger grit size showed better wear-resistance than that reinforced with the SiCp of smaller grit sizes. However, the SiCp/Cu matrix composite reinforced with larger SiCp lead to a more severe scuffing to the counterpart steel surface, which was characterized by more severe transfer and adhesion of the counterpart steel wear debris onto the SiCp/Cu matrix composites worn surface. Therefore, in terms of the comprehensive wear-resistance of the frictional pair, it was suggested to select the SiCp/Cu matrix composite reinforced with the SiCp size of 130㎚ to mate the AISI5140 steel.
