Pure magnesium was treated by A. C. treatment technique in 0.25mol/L NaZSO4+0.1mol/L NAOH solution. The surface morphology was observed by scanning electron microscopy. The contact angle of the treated surface of pure Mg was measured by the First Ten Angstroms instrument and then its surface free energy can be calculated. The effect of alternating current treatment on the corrosion resistance of the pure magnesium was studied through electrochemical methods in 0.05mol/L NACI+0.01mol/L NAOH solution. The experimental results showed that a uniform and perfect oxide film was formed after A.
