Abstract
PURPOSE: To carry out the above mentioned coloration of stable color tone, by treating with a fixed alternating current voltage at a specific voltage rising speed in the electrolytic bath containing hydroxyalkane (alkene) sulfonic acid and its metal salt, after carrying out anodic oxidation treatment of Al.
CONSTITUTION: Alternating current electrolytic treatment is carried out dipping Al or Al alloy in the electrolytic bath containing hydroxyalkane sulfonic acid or hydroxyalkene sulfonic acid shown in the formula I(R; saturated or unsaturated straight chain or branched chain C1W12 hydrocarbon part, OH and SO3H; chained on the optional carbon of the hydrocarbon) and its metal salt, for example, Sn salt, after carrying out anodic oxidation treatment of Al or Al alloy. On this occasion, boosting speed up to a fixed alternating current voltage, is made 0.8 volt/sec. or less. By this method, Al or Al alloy is able to color in a stable and uniform color tone.
