In this paper, we used ultrasonic to assist the fabrication of anodic aluminum oxide film. The anodic aluminum oxide film was prepared by using a two-step anodization procedure. The first step anodization was performed in 0.4 M C2H2O4 at 30 V and 4?. The second anodization condition was the same as the first step, we used ultrasonic at the second step. The anodic aluminum oxide film formation and dissolution rate were strongly affected the morphology of the film. Both of the reaction rate, however, is effect by the acid concentration, temperature, duration time, current density, anodization voltage, and ultrasonic. When we used the ultrasonic, we could get more uniform and higher pore density of anodic aluminum oxide film. The morphologies of anodic aluminum oxide membrane were investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM).
