Abstract: Two surfactants [cocomonoethnolamide (CMEA) and cocodiethnolamide (CDEA)] were used for inhibiting corrosion of mild steel in 1 M HCL by weight loss studies, Electrochemical polarization studies and Surface morphology by metallurgical research microscope. Weight loss studies, conducted at different temperatures (25°, 35° & 45°C) using various concentrations (50-250 ppm) of the inhibitor, revealed that the inhibitor efficiency increases with inhibitor concentration up to certain extent. Electrochemical polarization experiments revealed that all the compounds are anodic type inhibitors. Both the compounds have been found relatively good inhibitors. Inhibitor efficiency was found to vary with concentration and temperature.
