摘要：

Potentiodynamic polarization curve and electrochemical impedance spectroscopy (EIS) techniques were employed to investigate the corrosion electrochemical behavior of the different faces of AZ61 magnesium alloy rolled sheets in simulated sea water. The surface morphology of the level, the side and the cross section of the corroded rolled sheet was observed using scanning electron microscopy (SEM). Results show that the major corrosion form of the different faces is pitting for the rolled sheet in simulated sea water. The corrosion tendency of the three faces of the rolled sheet is level<side<cross section and their corrosion resistance order is opposite. The rolling brings about different effects on the microstructure of the three faces of the sheet, which determines their different anti-corrosion performance.
