Abstract：
The effect of sintering temperature and holding times on microstructure and properties of cobalt-based alloy were investigated by OM and Brinell-Rockwell hardness tester. The results show that the optimal sintering temperature and holding time for cobalt-based alloy are 1 290 ℃ and 2.5~3 h, respectively, and cobalt-based alloy has the best microstructure and mechanical properties.
