The results show that the resistance of transpassive film against the activation dissolution in acidic solution is much higher than that of passive film, and the breakdown potential of transpassive film can be strikingly enhanced by post-treatment. In addition, the effects of potential and post-treatment on the composition of surface film were investigated by means of AES and XPS analysis, and the relationship between the composition and stability of film was discussed too.
