Abstract：Galvanized steel specimen was immersed in saturated Zn(OH)2 seawater solution to simulate the corrosive environment, using the mass loss method, scanning electron microscopy (SEM), polarization curves and electrochemical impedance spectroscopy(EIS) to study the corrosion behavior of galvanized steel. The results showed that the membrane of the Zn coating was damaged because of the corrosion products Zn(OH)2 adsorption. With the increased of immersion time, the charge transfer resistance decreased and the corrosion current density increased during the corrosion reaction of galvanized steel. Pitting on the galvanized steel surface was induced by the adsorption of corrosion products Zn(OH)2.
