Abstract

The die casing Mg alloy with different washing and predisposing methods was treated by micro-arc oxidation process. The corrosion resistance of die casting Mg alloy specimen and products was investigated under different technical conditions. The factors influencing magnesium alloy corrosion resistance were also analyzed

and the ability to resist corrosion was compared with that of surface treatment in DACRO. The results showed that the surface treatment of micro-arc oxidation can fully meet the requirements of corrosion resistance for automobile housing under proper technical condition.
