| Abstract: | A new technology of CKS for forming conversion film on aluminum alloy was developed. The process of conversion coating formed by CKS was discussed by using electrochemical testing technology,and the distrituting laws of compostion and valency of cerium in the conversion film were probed by utilizing XPS at the same time. Then the mechanism of cerium-rich coating formed on aluminum alloy was presented. |
