Abstract Corrosion behavior of domestic galvanized steel in different reverse osmosis waters was investigated by means of open circuit potential measurement, electrochemical impedance spectroscopy and microstructure observation. The galvanized steel showed similar electrochemical characteristics during the failure process in different reverse osmosis waters produced with influent seawaters of different salinity. The corrosion process of galvanized steel was changed with the adjustment of the quality of reverse osmosis water via addition of calcium chloride, sodium chloride and sodium bicarbonate. Corrosion performance of the galvanized steel was related with falling off and adhesion of the formed corrosion products.
