摘　　要：研究稀土和锌对铜基粉末冶金滑板的影响。结果表明 ,稀土的加入可以提高滑板的硬度、耐磨性和耐蚀性 ,但滑板的冲击韧性略有降低。滑板硬度值可以通过控制主合金元素锌的加入量调节 ,从而满足各种不同接触线的要求。The effects of rare-earth elements and zinc on copper matrix slider made by powder metallurgy are investigated. The results show that the hardness, resistance to wear and resistance to corrosion of the slider are improved by the addition of rare-earth elements, at the same time, the impacting toughness is slightly decreased. The hardness of the slider can be adjusted by means of changing the content of zinc as the main alloying element, in order to fit the different touching wires.
