Influence of three different anions on morphology and property of trivalent chromium based conversion coating on aluminum alloy

摘要：

　　The influence of F-,C2O42- and Mo7O246- as film agents on the morphology and the electrochemical property of trivalent chromium based conversion coating was investigated with the methods of scanning electronic microscope(SEM),contact angle measurement and electrochemical test.From the SEM micrograph we observed various morphologies and properties for the Cr(Ⅲ)/based CCC on aluminum alloy among the specimens immersed in different solutions,and the specimen in Cr(Ⅲ)/Mo7O246- solution displays a much smooth and dense morphology without notable crevices.The electrochemical tests showed that the anti-corrosion properties are also varied among the coatings formed in different conversion solution,which is attributed to the different role of each agent.
