Development of Conductive Anodic Oxidation Coatings on AZ91D Magnesium Alloy

Abstract:

AZ91D magnesium alloy was anodized in an electrolytic solution with phosphate as the main component. The conductivity and structure of the obtained coatings were examined. The anodic oxidation coatings are found to be composed of Mg, O, Al, and P. By controlling the phosphorus content, conductive coatings could be formed with surface resistivities of 0.2 ' or less. XRD analysis and TEM observations reveal that the structure of the conductive coatings is amorphous.
