Magnesium alloy was prepared by micro-arc oxidation in the NaAlO2 ,KH2 PO4 compround system adding different concentrations of sodium lactate. Variation rules of the growth rate of ceramic layer with sodium lactate concentration were studied. Morphology and structure of the ceramic layer were observed by SEM. The phase composition of film was analyzed by XRD. The potentiodynamic polarization curves were tested by the electrochemical workstation. The results show that when concentration of sodium lactate is 3 mL/ L,the denseness of ceramic coating is good,and the corrosion resistance of ceramic coating is the best.
