MAGNESIUM OR MAGNESIUM ALLOY ARTICLE HAVING ELECTROCONDUCTIVE ANODIC OXIDATION COATING ON THE SURFACE THEREOF AND METHOD FOR PRODUCTION THEREOF

摘要

The invention provides a product, in particular to a magnesium or magnesium alloy product with an anode oxydation coating with conductibility and excellent erosion resistance on the surface, comprising magnesium or a magnesium alloy. The magnesium or magnesium alloy product is characterized in that: an electric anode oxydation coating is arranged on the surface of the magnesium or the magnesium alloy, and the resistance value of the coating surface, mensurated between the two terminals with a mutual distance of 10mm, is below 100 Omega; the magnesium or the magnesium alloy is dipped in the electrolyte with a pH value of 8 to 14 comprising phosphate radical of 0.1 to 1mol/L and ammonia ion or ammonium ion of 0.2 to 5 mol/L, and an anodic oxydation treatment is processed on the surface of the magnesium or the magnesium alloy, and then the product can be manufactured.
