Abstract
PURPOSE: To prevent the deterioration of an Sn electrolytic bath due to the oxidation of Sn ions in the bath by separating an Al material and an opposite electrode by an ion exchange membrane when the Al material is oxidation- colored by anodic electrolysis using the Sn bath.
CONSTITUTION: When an electric current is supplied between an Al material 1 as an anode and an opposite electrode 2 in an electrolytic bath of stannous sulfate or the like to form a colored oxide film on the surface of the material 1, both the electrodes 1, 2 are separated by an ion exchange membrane A. The membrane A may be an anion or cation exchange membrane. Thus, the oxidation of Sn2+ ion in the bath to Sn4+ ion is prevented, the reduction of the oxidation coloring power of the bath due to electrolysis is prevented, and the life of the bath is elongated.
