Title:
COLORED ALUMINUM MOLDED BODY AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2017025384
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aluminum molded body with a sufficiently colored film by filling a pigment into pores formed by anode oxidation without generating spalling.SOLUTION: Provided is a colored aluminum molded body and a method for producing the same characterized in that an aluminum molded body 1 is subjected to anodic oxidation treatment in which a current value is fixed and the subsequent anodic oxidation treatment in which a volume value is fixed to form an anodic oxide film 2 having pores 3, L on the surface of the aluminum molded body 1, the aluminum molded body 1 is immersed into an aqueous solution of a metal organic complex or the like, AC current is conducted to precipitate and fill a pigment 4 of titanium oxide or the like at the inside L of the formed pores, at this time, electrodeposition is performed while increasing voltage at a prescribed rate from the point of the start of the conduction to a fixed time, or electrodeposition is performed in such a manner that voltage is increased at a prescribed rate from the point of the start of the conduction to a fixed time, and performed under the conditions of fixed voltage on and after the passage of the fixed time.SELECTED DRAWING: Figure 1
