The anticorrosive property of anodizing oxide film on aluminum alloys could be improved by adding rare earth additives in anodizing solutions.And excellent sealing effects were shown when anodized aluminum alloys were sealed in rare earth metal salts solutions.The application prospects of rare earth elements in aluminum alloy surface treatments were promising.In this paper the application situation of rare earth elements in anode oxidation and post treatment process of aluminum alloys were reviewed.Problems of future development were pointed out in accordance with current research situation.
