Abstract

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.
