ANODIC OXIDE FILM AND METHOD FOR PERFORMING SEALING TREATMENT THEREON

摘要

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.

1. A method for performing a sealing treatment on an anodic oxide film, the method comprising the steps of:
applying direct current electrolysis to an aluminum-based material to form a second anodic oxide film; applying, after the step of applying direct current electrolysis, AC-DC superimposition electrolysis to the aluminum-based material to further form a first anodic oxide film; and performing a sealing treatment on the first and second anodic oxide films with a solution containing lithium ions.
