Anodic oxide film and method for performing sealing treatment thereon
Provided are an anodic oxide film of an anodic oxide film of an aluminum-based material and a method for performing a sealing treatment on the anodic oxide film which can achieve both high corrosion resistance and high repairing ability. A method may comprise applying direct current electrolysis to an aluminum-based material to form a second anodic oxide film. After which, an AC-DC superimposition electrolysis may be applied to the aluminum-based material to further form a first anodic oxide film. A sealing treatment may then be performed on the first and second anodic oxide films with a solution containing lithium ions.
