Abstract
PURPOSE: To electrolytically color Al in a colorful tone, by carrying out electrolytic treatment of Al by using an AC of a specified condition in the sulfuric acid bath after carrying out the anodic oxidation treatment and next, carrying out the AC electrolytic treatment in the electrolytic bath containing tin salt and sulfuric acid.
CONSTITUTION: Anodic oxidation coating is formed on the surface of Al by carrying out the DC electrolytic treatment of Al in the sulfuric acid bath. Next, electrolytic treatment of Al is carried out until the electrolytic voltage is reached at nearly constant value of ≤3V by using an AC of current density of the range defined by 6.5×10-4×f≤i≤4.3×10-3×f+0.4 (i; current density A/dm2, f; frequency Hz) in the range defined by the 20W2,000Hz frequency in the sulfuric acid bath. By the above described intermediate treatment, structure of the oxidized coating is reformed. Further, AC electrolytic treatment of Al is carried out in the range defined by 3W18V in the electrolytic bath containing tin salt and sulfuric acid. Color tone of obtained colored coating is colorful from vivid yellow to deep blue or green and basic color tone is determined by the electrolytic condition at the intermediate treating process.
