Corrosion inhibition effect of 2- [4-(methylthio) phenyl] acetohydrazide (HYD) and 5-[4- (methylthio)benzyl]-4H-1,2,4-triazole-3-thiol (TRD) on zinc in 0.1 M HCl was studied by using mass loss, polarization and electrochemical impedance spectroscopy (EIS). Effect of concentration and temperature was evaluated by mass loss method. Results indicated that the compounds are efficient, mixed type but predominantly anodic in nature. Similar trend was observed in both chemical and electrochemical results. TRD shows good inhibition efficiency than HYD. Obtained results were justified from the study of surface morphology.
