Abstract

An anodizing method for growing an anodized layer on a surface of aluminum in electrolyte is disclosed. The method comprises applying a DC/AC-combined pulse wave between an anode and a cathode. The DC/AC-combined pulse wave is provided by combining a DC pulse wave with an AC wave, and has a peak voltage at a start point of each pulse. The grown anodized layer may be equal to or less than 300μm in thickness, and the diameter of a cell in the anodized layer may range between 50nm and 100nm. The power supply used for anodizing may comprise a rectifying modulator unit, an AC modulating unit, a pulse wave synthesizing unit, and a control unit.
