In this paper, micro-arc oxidation process on magnesium alloy anode in three models alkaline solutions are considered under conditions of low power. The excellent morphology of ceramic coating is dense smooth film-like structure of the whole. The phase composition of ceramic coating film is MgO, Al2O3, and a kind of phase composition of the main salt. In the constant current mode in a high frequency of small duty cycle of research methods, the corrosion performance (salt spray test) is successfully developed that achieve 800~ 1000 hours of high quality film, under electric current density less than 1A/dm2.
