在Ｍｏ￣＋＋Ｎ￣＋注入模式的基础上，应用电子能谱、卢瑟福背散射谱、扫描电子显微镜和ＭＨＫ－５００型摩擦磨损试验机等研究了加注稀土元素铒正离子Ｅｒ￣＋对轴承表面摩擦学性能和耐蚀性能的影响．结果表明，在合理配置Ｍｏ￣＋、Ｎ￣＋、Ｅｒ￣＋之能量和剂量的情况下，加注Ｅｒ￣＋既能更好地改善轴承的表面性能，又能使重离子的强韧化效果提高２－４倍以上，表明Ｍｏ￣＋＋Ｎ￣＋＋Ｅｒ￣＋注入模式是一种具有良好应用前景的轴承表面强韧化方法。
Based on the Mo ~ ++ N ~ + implanted mode, the effects of Er + + ion donating with rare earth element erbium ion were studied by using electron spectroscopy, Rutherford backscattering spectroscopy, scanning electron microscopy and MHK-500 friction and wear testing machine. Bearing surface tribological properties and corrosion resistance. The results show that Er ¯ + can not only improve the surface properties of the bearing but also increase the toughness of the heavy ions when the energy and dosage of Mo ¯ +, N ¯ +, Er ¯ + The effect is improved by more than 2-4 times, indicating that Mo ~ ++ N ~ ++ Er ~ + injection mode is a kind of bearing surface toughness method with good application prospect.
