Abstract: Electrochemical properties of zinc, copper and brass were comparatively investigated in 0.1 M NaCl and 0.1 M NaCl containing tolyltriazole (TTA) and benzotriazole (BTA).Electrochemical behavior of brass in these medium resembles to copper. TTA hinders corrosion of brass by adsorption and enhancing ZnO formation on the surface. A mechanism is proposed by the help of solution analysis after constant potential electrolysis and potentiodynamic polarization curves.
