Combined with the observation of the metallograph and analysis of the change of chemical composition of alloys,we can draw the following conclusion:the addition of within the range of 40% once-used cobalt-chromium alloy to casting cobalt-chromium alloy wouldn't affect the quality of restorations,excessive addition of once-used alloy would damaged the microstructure and physical properties.

摘 要：通过比较不同比例的新旧钴铬合金铸造后的抗拉强度、屈服强度、延伸率、硬度等机械性能指标，并结合相应的金相观察及化学成份分析，得出结论：铸造钴铬合金中可加入不超过40％的仅铸造过一次的旧料而不影响合金的主要机械性能，超过这一比例，将影响修复体的质量。

The amount of Ni and Cr released from specimens coated with gold was much fewer than those from unplated specimens (P .05), which meant the stability of Ni-Cr alloy on the surface was improved. The biocompatibilities of gold-coated Ni-Cr alloy were better than the uncoated alloy, though there was no difference in biological ranking.
