| Abstract: | To investigate the effect of oxide film state on its electrochemical characteristic,the electrochemical performance of anodic aluminum oxide film on high purity aluminum was studied in the buffer solution of sodium dihydrogen phosphate by using electrochemical method.The results indicated that the cathodic polarization process of the oxide film could be divided into three stages.In the initial stage,the current density was small and the potential shifted to the negative quickly.In the second stage(hydrogen ... |
