MAGNESIUM OR MAGNESIUM ALLOY PRODUCT AND METHOD FOR PRODUCING SAME

摘要

A magnesium or a magnesium alloy product is disclosed which is produced by directly forming a metal plating film on a conductive anodic oxide coating which is formed on the surface of a magnesium or magnesium alloy. By immersing the magnesium or magnesium alloy in an electrolytic solution with a pH of 8-14 which contains 0.1-1 mol/L of a phosphoric acid radical, a conductive anodic oxide coating is formed on the surface of the magnesium or magnesium alloy through anodic oxidation, and consequently the surface can be subjected to electroplating. As a result, there is obtained a magnesium or a magnesium alloy product which is covered with a metal plating film having excellent corrosion resistance and adhesiveness.
