摘要
将铝合金稀土转化膜成膜工艺用作阳极氧化后处理工艺.多种实验结果表明,阳极氧化后经稀土处理,膜的耐蚀性有明显的提高,铈盐对多孔氧化膜层具有封闭作用,其封闭效果可与常温封闭方法相比拟.
The rare-earth conversion film forming technology for aluminum alloy was taken as an aftertreatment method of anodizing. The results of several experiments showed that the corrosion resistance of film is increased evidently aftertreatment by rare-earth salts. The sealing action to porous anodizing film is provided by cerium salt. The effectiveness of the sealing can compare with the normal temperature sealing.
