Application of Cerium Salt in Aftertreatment Process for Anodizing of Aluminum Alloy
-
摘要: 將鋁合金稀土轉化膜成膜工藝用作陽極氧化后處理工藝.多種實驗結果表明,陽極氧化后經稀土處理,膜的耐蝕性有明顯的提高,鈰鹽對多孔氧化膜層具有封閉作用,其封閉效果可與常溫封閉方法相比擬.Abstract: 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.
