Abstract

An important method of protecting metallic materials against deterioration due to acid corrosion is by the use of corrosion inhibitors. In the present investigation, corrosion inhibition study of two compounds,1-(2-hydroxyethyl)-2-ethylimidazoline(Inh I) and 1-(2-hydroxyethyl)-2-decylimidazoline (Inh II) have been performed for oil-well tubular steel  (N80) in 15% HCl using weight loss, electrochemical polarization, AC impedance and SEM. The inhibition efficiencies of the inhibitors follow the sequence, Inh II > Inh I. The results showed that inhibition efficiency of all inhibitors increased with increase in their concentration in 15% HCl solution. Both inhibitors act as mixed inhibitors and obey the Langmuir adsorption isotherm. The corrosion inhibition mechanism follows the adsorption phenomenon.
