摘要
In the electrolytic oxidation treatment method that iterates the yin yang alternating electrolytic with a time constant of continuity in an electrolytic solution to the metal material capable of forming an oxide film by anodic oxidation method, containing an alkali metal hydroxide, positive negative I do Continuous step of 2 or more stages shadow current density is different from each of the electrolytic process in the shade alternating electrolysis. The invention described above, can also to Mg alloy of 90 wt% or less, a single processing step, the composition ratio of magnesium to form a surface treated film of a single layer with good corrosion resistance and electrical conductivity it becomes.
