| 摘 要： | 研究了稀土对电沉积Ｎｉ－Ｐ合金度层耐蚀性及组织的影响，通过浸泡实验和极化曲线的测定。得出在镀液中添加一定量的稀土元素能显著改善镀层的耐蚀性能。ＸＲＤ，ＴＥＭ，ＥＤＳ结果表明，稀土元素具有促进Ｎｉ－Ｐ合金形成非晶组织的作用，由于稀土的加入，在远低于８％的Ｐ含量下，获得了以非晶态为主的组织。

| Abstract: | The effects of RE on the corrosion resistance of electro plating Ni P alloy coating were investigated. Immersion test and polarization curves show that the corrosion resistance of the coating can be improved obviously with a certain amount of RE in the bath. The XRD, TEM, EDS composition analysis show that RE can improve the amorphism of the Ni P alloy coating. With the addition of RE elements, the amorphous structure of coating can be obtained when the P contents are lower than 8%. |
