AbstractCorrosion inhibition of tolytriazole for galvanized steel was studied in 5mM NaCl by using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS), scanning vibrating electrode technique (SVET). The results of EIS and polarization tests indicate that tolytriazole is effective in corrosion inhibition of galvanized steel. As the concentration of tolytriazole is increased to 0.01M, the inhibiting efficiency reaches above 98%. The low values of anodic and cathodic current density in SVET maps suggest that the complex of tolytriazole with galvanized steel inhibits the anodic and cathodic reactions of corrosion of zinc. The adsorption behaviour of tolytriazole is found to conform to Langmuir adsorption isotherm, which is typical chemical adsorption.
