Abstract
Porous anodic alumina film was prepared in sulfuric acid electrolyte and scanning electron microscope(SEM)was used to observe the surface morphology.The effect of preprocessing and two-step anodization on anodic alumina film was investigated respectively.The experimental results indicate that the well ordered porosity resulted from the preprocessing and two-step anodization.
