摘要	The corrosion and electrochemical behavior of extruded AZ31D magnesium alloys in NaCl solution were investigated using SEM, XRD and electrochemical method. It is found that AZ31D is susceptive to Cl- ion, and the open circuit potential shifts to more negative values with increasing chloride concentration. Pitting occurs at corrosion potential and corrosion area enlarges with enhanced polarization. Tafel slopes of the cathode branches in different testing solution are almost the same. Cl- concentration affects cathode course slightly High frequency capacitive loops shrink with the increase of Cl- concentration. Corrosion initiates from the grain boundary and spreads to entire surface with time.
