| Abstract: | An optimized zinc series phosphating formula for chrome-free phosphating of magnesium alloy was gained through orthogonal test.The phosphating film showed a needle-like microstructure under scanning electron microscope.The result of EDS showed that the main composition of the film was zinc phosphate.The results of corrosion test and electrochemical measurement showed that the corrosion resistance of magnesium alloy was significantly improved by this optimal phosphating treatment. |
