稀土对电刷镀Ni-P合金组织结构的影响

Influence of RE Element on Structure of Electro-Brush-Plating

摘要: 研究了在晶态Ni-P合金刷镀液中添加稀土后,镀层组织结构上的变化,X射线衍射及透射电子衍射分析表明:在镀液中添加一定量的稀土可显著提高镀层中的非晶态组织比例,其变化规律与相应的镀层耐蚀性能变化规律是一致的,并讨论了可能的机理。

Abstract: The change on the structures of Ni-P alloy coating with different amount of RE in the solution has been investigated.X-ray and TEM analysis showed the ratio of amorphism structure in the coating can be improved obviously with a certain amount of RE in the bath.And its changing law was the same as the changing law of the coating corrosion resistance.The probable mechanism was also discussed.
