Abstract
In the present work, pure Cu and Cu/SiCp metal matrix composites were prepared by sintering and sinter–forging processes. The tribological behaviour of copper and Cu/SiCp composites was studied using a pin–on–disk tester. The influence of SiC particles and fabrication type on the tribological behaviour of pure Cu and Cu/SiCp metal matrix composites were studied. Dry sliding wear tests represented that the composites with 60 vol. % SiC exhibits a lower wear loss compared to other compacts. This was due to the reinforcing SiC particulates being effective to reduce the extent of wear deformation in subsurface region during sliding. Moreover, the results indicated that applying external compressive force during the sintering process of Cu and Cu/SiCp compacts has an important effect on reducing and eliminating porosities and reach to a high final density. Therefore, wear loss of the samples produced through sinter–forging process was improved significantly compared to conventionally sintered samples.
