The Development and Mechanism of Micro-Arc Oxidation Process in Magnesium Surface

Abstract:

In this study, a constant current density was used in magnesium microarc oxidation treatment. The microstructure, chemical composition, phase composition and corrosion resistance of the micro-arc oxidation film were characterized by XRD and EDS. The experimental results showed that the test pieces of magnesium would formed an silver-gray uniform densification oxide film on the surface, the film-formed materials was amorphous by XRD analysis, and on this basis we preliminary discused the film-forming mechanism.
