Abstract

PURPOSE: To partially etch anodic oxidation films and form streak-form patterns by subjecting the Al material having been applied with anodic oxidation film treatment to DC electrolysis treatment in an electrolytic bath containing alkali metals of inorganic acids or organic acids or the like.
CONSTITUTION: After Al or Al alloy is subjected to anodic oxidation film treatment, it is dipped in the electrolytic bath of about pH 1W6 containing salts of alkali metals or alkaline earth metals of inorganic acids or orgainc acids. With the Al as cathode, it is subjected to electrolysis treatment by DC or current waveform having equivalent effect, whereby the anodic oxidation films are etched in streak form in the vertical directions. If the concentration of the compound in this electrolytic bath, its, pH, solution temperature, treating time, etc. are selected, the arbitrary streak patterns such as short and long ones, broad and narrow ones are formed in the anodic oxidation films. If colored films are formed on this streak pattern forms, the beautiful colored streak patterns are formed.
