Abstract Abstrat: The electrochemical behavior of AZ31 alloy in Mg(ClO4)2 solution with different additives was investigated by polarization curve, electrochemical impedance, constant current discharge and immersion corrosion tests. The results showed that the addition of NaF makes the open circuit potential and activation potential more negative, decreases the corrosion current in the polarization curve and corrosion rate in immersion test, increases the discharge efficiency, and especially shortens discharge hysteresis time. In contrast, the addition of La（CH3COO）3 increases the discharge efficiency, but has no beneficial effect on the discharge hysteresis and corrosion resistance of the alloy.
