【摘要】 本文对钴铬合金铸后在金相组织、硬度、抗腐蚀性能等方面进行研究。实验表明钴铬合金经过一、二次铸造后其金组织结构未发生变化，但其晶粒发生长大，硬度无明显改变，且有较高的抗腐蚀性能。本研究为钴铬合金的回收再利用提供了可靠的理论依据。更多还原

【Abstract】 We studied the metal tissue, hardness, resistance of Co-Cr alloy after casting. It was found that there was no change in metal tissue and hardness of Co-Cr alloy after first and second casting, however.Its grains grew up with high resistance proprety. Our study provide valuable basis of the theory for recovering and using Co-Cr alloy.更多还原
