摘要
研究了稀土对电刷镀Ｎｉ－Ｐ合金耐蚀性能及组织的影响，浸泡实验和极化曲线表明：在镀液中添加一定量的稀土能显著改善镀层耐蚀性能，Ｘ射线、透射电子显微镜及能谱表明：稀土元素具有促进Ｎｉ－Ｐ合金形成非晶组织的作用，并提出了稀土促进非晶化的可能机理。
The effects of the Rare Earths(RE) on the corrosion resistance and structure of the electro brush-plating Ni-P alloy coating have been investigated. The results obtained from the immersion test and the polarization curves showed that the corrosion resistance of the coating could be improved obviously with a certain amount of RE in the bath. The X- ray,TEM, EDS composition analysis showed that the RE could improved the amorphism of the Ni-P alloy coating. And the probable mechanism of the RE to improve the amorphism has been proposed.
