ABSTRACT:
An important method of protecting metallic materials against deterioration due to corrosion is by the use of corrosion inhibitors. In the present investigation, corrosion inhibition study of two imidazoline derivatives, 1-(2-hydroxy ethyl)-2-methylimidazoline (Inh I) and 1-(2-hydroxyethyl)-2-decylimidazoline (Inh II)) have been performed for oil-well tubular steel (N-80) in 15% HCl using weight loss, electrochemical polarization and SEM techniques. The inhibition efficiencies of the inhibitors follow the sequence, Inh II > Inh I. The results showed that inhibition efficiency of both the inhibitors increased with increase in inhibitors concentration. Both inhibitors act as mixed inhibitors and obey the Langmuir adsorption isotherm. Corrosion inhibition mechanism take place through adsorption phenomenon.
