Abstract
The corrosion inhibition efficiency of ethyl-2-amino-4-methyl-1,3-thiazole-5-carboxylate (EMTC) has been studied to prevent the corrosion of AA6061 alloy in 0.05 M HCl solution by weight loss, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (Tafel) methods at temperatures 303–323 K. Ethyl-2-amino-4-methyl-1,3-thiazole-5-carboxylate acted as a mixed-type inhibitor, and its efficiency increased with the increase in inhibitor concentration and temperature. Chemisorptions on the metal surface are revealed by kinetic and thermodynamic parameters. A surface morphology study of polished, corroded and inhibited metal surfaces verified the formation of a protective film.
