The effect of triazoles and surfactants on the corrosion inhibition of carbon steel in acid solution

Abstract

The inhibitive action of triazoles and surfactants on the corrosion of carbon steel has been studied using the weight loss method and electrochemical studies. Results obtained show that these organic compounds are very good inhibitors. Potentiodynamic polarisation studies clearly reveal the type of inhibitor. The corrosion parameters such as corrosion current (i_corr), corrosion potential (E_corr), inhibition efficiency (IE), corrosion rate, and activation energy (E_a) were calculated at different temperatures ranging from 303 to 333 K. The adsorption of triazole compounds on carbon steel surface obeyed Langmuir's adsorption isotherm.
