A Technology of eco-friendly chemical conversion coating on magnesium alloys by phosphate-permanganate was studied. The performances of blank sample and chrome-free chemical conversion coating on Mg-based alloys were studied. The morphology and corrosion resistance of chemical conversion coating were tested by metallographic microscope and corrosive test. The best technology condition is that the concentration of KMnO4 is 20g/L, Na3PO4 is 100g/L, KF is 40g/L, and the pH is 7~8, the temperature is 50°C．The time of the chemical conversion is 40min.
