文摘

Cu and Cu/SiC_p composite compacts were prepared through sintering and sinter-forging processes. Influence of SiC particles and fabrication type on the tribological behavior of pure Cu and Cu/SiC_p composites was investigated. Dry sliding wear tests represented that the sinter-forged Cu composite compacts with 60 vol.% SiC exhibit the lowest wear loss compared to other compacts. Moreover, the results indicated that applying compressive force during sintering process of Cu and Cu/SiC_p compacts has a significant effect on reducing and eliminating porosities and achieving to higher bulk density. Therefore, wear loss of the Cu and Cu/SiC_p compacts produced through sinter-forging process was improved significantly compared to conventionally sintered Cu and Cu/SiC_p composite compacts.
