摘要

The discharge and corrosion performance of AP65 magnesium alloy in simulated seawater with different temperatures is investigated by electrochemical techniques and corrosion morphology observation. The results indicate that AP65 alloy can hardly be activated at a large current density in the 0 A degrees C simulated seawater, whereas the activation time is shortened, and the potential exhibits a significantly negative shift in the 35 A degrees C simulated seawater. However, the increase in temperature promotes the localized corrosion and thus is detrimental to the anode efficiency of AP65 alloy. Moreover, the effect of seawater temperature and current density on the surface morphology of AP65 alloy during the discharge process is also analyzed.
