Porous oxides or nanotubes are obtained through the anodization of valve metal. However, the mechanism of nanotube growth remains unclear. Traditional field-assisted dissolution (FAD) theory has many limitations, such as its inability to explain the connotation of the three stages in the current–time curve. By placing a container between two electrodes, the ions move around the container in a ring in the present study. The potential gradient during anodization was innovatively changed. Finally, the current–time curve obtained during anodization using the new device is quite different from that obtained using conventional anodizing device. This phenomenon is explained by the electronic current and ionic current theory in this paper. |
