稀土在铜及铜基合金中的作用

The Effect of Rare Earth on Copper and Copper Based Alloys

稀土作为一种重要的工业原料在铜和铜合金中有着重要的价值,稀土在铜及铜基合金中能起脱气除杂的作用,能改善铜及铜基合金显微结构,提高其强度和硬度及增强热稳定性,还能增强铜合金的耐腐蚀和耐磨性能。

Rare earth has important values in copper and copper based alloys,it can reduce the impurities and release the gases in the copper and alloys, improve the microstructure, increase the strength and hardness and thermal stability, and strengthen the anticorrosion and wearablity of the copper and copper-based alloys.
