Abstract
The inhibition performance of clove oil (CLO) on mild steel (MS) in 2 M H3PO_4 was studied by weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The adsorption of inhibitor on MS surface obeyed the Langmuir’s adsorption isotherm. Potentiodynamic polarization measurements showed that CLO is mixed type.The optimum concentrationof 1g/L can decrease the corrosion of material with the efficiency of 87%. The scanning electron microscope (SEM) observations confirmed the existence of a protective film of inhibitor on MS surface. The adsorption behavior of the inhibitor on Fe surface has been studied using molecular dynamics (MD) method and density functional theory. The results indicated that the inhibitor could adsorb on the Fe surface firmly through the benzene ring and two oxygen atoms.
