Özet

In this study, the effect of benzotriazole (BTA) and tolytriazole (TTA) as inhibitors on the corrosion of pure zinc metal was investigated by electrochemical potential-time, current-potential and AC-impedance methods in 1M NaCl solution. Corrosion rates of metal in the studied solutions were obtained by extrapolation of Tafel zones of current-potential curves to the corrosion potential and inhibition effects were calculated from corrosion rates obtained in studied corrosive media. Inhibition effects of benzotriazole and tolytriazole are dependent to the concentration of the these triazolic compounds in the studied solutions. Inhibition effect as percentage is higer than 90.
