ABSTRACT

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.
