Influence of RE Element on Structure of Electro-Brush-Plating
-
摘要: 研究了在晶態Ni-P合金刷鍍液中添加稀土后,鍍層組織結構上的變化,X射線衍射及透射電子衍射分析表明:在鍍液中添加一定量的稀土可顯著提高鍍層中的非晶態組織比例,其變化規律與相應的鍍層耐蝕性能變化規律是一致的,并討論了可能的機理。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.
