ABSTRACT: The inhibiting effect of N-decyl-3-amino-1,2,4-triazole (TN10) against Copper corrosion in aerated 3%NaCl, has been developed. Potentiodynamic measurements and electrochemical impedance spectroscopy have been applied to determine the corrosion rate. Scanning electron microscopy (SEM) studied surface morphology has been also used to characterize electrode surface. The obtained results indicate that TN10 acts as a good mixed-type inhibitor retarding both anodic and cathodic reactions. An increase of TN10 concentration leads to a decrease of corrosion rate and inhibition efficiency increase.
