“…A chemisorption is a strong interaction in which the electronic states of the inhibitor molecules hybridize with the metal electron state [43][44][45][46][47][48][49] . The interaction between BTAH and metal surface is associated with the π-electron of BTAH and the d-orbital of metal surface, which could be regarded as the chemisorptions.…”

The corrosion inhibition effect of benzotriazole on copper and steel in simulated tap water was investigated by using potentiodynamic polarization, electrochemical impedance spectroscopy and a quantum chemistry analysis. The corrosion inhibition ef ciency for copper and steel was accordingly increased with an increasing of the benzotriazole concentrations. However, the electrochemical test showed a signi cant difference between the inhibition ef ciency of copper and steel. From molecular theory and the adsorption isotherm, the difference between the d-orbital structure of copper and steel affects the adsorption stability of benzotriazole on the metal surface. This postulation is well correlated with the results of the quantum chemical analysis.

“…As can be seen in this figure, the impedance diagrams in the Nyquist plot become larger with time. The increase of the polarization resistance with the immersion period is often reported for the inhibiting action of heterocyclic on copper corrosion [5][6][7]9,10]. However the cording to an order ascending:…”

“…Many papers reported that heterocyclic compounds, such as azole, reveal marked inhibition efficiency [1][2][3][4][5][6][7][8][9][10][11][12]. In a neutral chloride medium, Otmacic and Stupnišek-Lisac examined the inhibiting effect of non-toxic imidazoles derivatives, and showed that those containing phenyl groups showed a better performance [7]. El Issami et al studied the inhibiting effect of triazoles (triazole, amino-triazole and diamino-triazole) in hydrochloric acid, and they found that the diamino-triazole has the best performance [8].…”

Some azoles were tested such as 3-amino-1,2,4-triazole (ATA), 3-4'-bitriazole -1,2,4 (BiTA)and 2-Mercaptobenzimidazole (MBI) against Cu-30Ni alloy corrosion in 3%NaCl polluted by ammonia using potentiodynamic measurements and electrochemical impedance spectroscopy and non-electrochemical techniques (scanning Electron Microscopy (SEM)) studied surface morphology has been used to characterize electrode surface. This study permitted to follow the evolution of the inhibitory effect of some azoles, on Cu-30Ni alloy corrosion in 3% NaCl polluted by ammonia and indicate that the tested inhibitors act as a good mixed-type inhibitor retarding the anodic and cathodic reactions. An increase of the inhibitors concentration leads to a decrease of corrosion rate and inhibition efficiency increase.
