Abstract
PURPOSE: To color the anodic oxidation coating in various color tone, by dipping Al (alloy) is warm solution of metal salt after carrying out coating chemical treatment of Al (alloy) by the electric current inversion electrolysis carried out the polarity conversion periodically in sulfuric acid or electrolyte containing sulfuric acid, and accumulating S compound in the coating.
CONSTITUTION: Anodic oxidation coating is formed on the Al (alloy) 5 by the electric current inversion electrolysis converting the polarity of the carbon bord 4 periodically, that is, positive current from the power source 6 in sulfuric acid or electrolyte containing sulfuric acid in the electrolytic bath 3. And S compound is accumulated in the coating by the negative current. Next, the above coating is colored by dipping in warm solution containing metal salts of Ni.Co.Pb etc. or sealing treatment is carried out after dipping in the above solution. By the above method, high hardness smooth coating is formed by the chemical treatment at high speed under high temperature. high current density electrolysis and also, coloring of deep color tone is easily obtained by the coating chemical treatment in a short time.
