摘　　要：配制一定比例的钴基合金粉末,利用光学显微镜、布洛硬度仪等分析手段研究烧结温度和保温时间对钴基合金微观组织和硬度的影响。结果表明,烧结温度为1 290℃,保温时间为2.5～3.0 h时,钴基合金具有最佳的微观组织且硬度最高。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.
