本文介绍了铜铅轴承合金添加重稀土氧化物及硅稀土合金的研制工艺。讨论了稀土元素对铜铅铸件的机械性能、耐磨性能及金相组织的影响,并对这两种稀土添加剂进行了比较。 This article describes the development of copper-lead bearing alloys with rare earth oxides and silicon rare earth alloys. The effects of rare earth elements on the mechanical properties, wear resistance and microstructure of copper-lead castings were discussed. The two rare earth additives were compared.
