2A12 alloy by MAO on main salts electrolyte system of phosphate sodium is investigated. By contrast test, the influences of arc starting voltage, the thickness of the ceramic layer , growth rate, and wear resistance with different K2Cr2O7concentration are analyzed. If K2Cr2O7concentration is 2.5g/L , the arc starting voltage reached the lowest, the surface topography is the best, the wear resistance is the well.
