Electrochemical Studies of Corrosion Inhibition of Mild Steel: Corrosion Inhibition of Mild Steel in One Molar Sulfuric Acid Solution Using Some Triazole Derivatives

The corrosion inhibition of steel in 1.0 M sulfuric acid by some triazole derivatives namely, 4-amino-1,2,4-triazole-3-thiol (ATT), 4-amino-5-methyl-1,2,4-triazole-3-thiol (AMTT) and 4-amino-5-ethyl-1,2,4-triazole-3-thiol (AETT) has been studied using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and Scanning electron microscopy (SEM). The results revealed that the inhibition efficiency increases as the inhibitor concentration increases and follows the order (ATT
