Abstract
The corrosion behavior of aluminum and its inhibition by 3-amino-1,2,4-triazole-5-thiol (ATAT) in naturally aerated stagnant Arabian Gulf water was reported. The work was carried out using electrochemical impedance spectroscopy (EIS), cyclic potentiodynamic polarization (CPP), and potentiostatic current–time (CCT) measurements. EIS data indicated that ATAT decreased the corrosion of Al by increasing the solution and polarization resistances, the impedance of the interface and the maximum degree of phase angle. ATAT was also found to decrease the cathodic, anodic, and corrosion currents and corrosion rate as well as increase the polarization resistance of Al as confirmed by the CPP and CCT measurements.
