Abstract (en)
Disclosed is a method of surface-treating an aluminum alloy, including pretreating an aluminum alloy; immersing the pretreated aluminum alloy in an etching solution having a predetermined composition so that the surface of the aluminum alloy is etched, thus forming a transparent glossy film; subjecting the aluminum alloy having the transparent glossy film to anodic oxidation, thus forming an oxide film on the surface of the aluminum alloy; and post-treating the aluminum alloy having the oxide film.
