Abstract

Warm compaction powder metallurgy was used to produce a $Ti_3SiC_2$ particulate reinforced Cu matrix composite. Fabrication parameters and warm compaction behaviors of Cu powder were studied. Based on the optimized fabrication parameters a Cu-based electrical contact material was prepared. Results showed that in expend of some electrical conductivity, addition of $Ti_3SiC_2$ particulate increased the hardness, wear resistivity and anti-friction ability of the sintered Cu-base material.
