Abstract

Abstract—A new Lavandula angustifolia extract was prepared to investigate the anti-corrosion effect against mild steel in corrosive environment. Inhibitory performance of green extract was examined in detail with electrochemical, morphological, as well as quantum chemical calculation analyses. The effects of inhibitor concentration and exposure time were examined to describe the inhibition behavior. Physical and chemical adsorption kinds happen between the surface of the steel and Lavandula angustifolia extract. Furthermore, surface analysis studies were applied to justify the formation of protective adsorption coating occurred on the surface of steel. Quantum chemical calculation results are also in good consistent with other experimental outcomes.
