Abstract :The role of lavender extract in the present study is to examine the effect of inhibiting the corrosion of mild steel in the ambient conditions with its green and eco-friendly effect. It was determined the influence of inhibitor using electrochemical impedance spectroscopy insert ignore into journalissuearticles values(EIS); in different immersion times. From the EIS measurement results, it was observed that as the concentration of Lavandula extract in the HCl solution increased, the polarization resistance insert ignore into journalissuearticles values(Rp); values in the EIS diagram increased. Finally, scanning electron microscope insert ignore into journalissuearticles values(SEM); analysis was conducted to better clarify the surface inhibition of the electrode containing Lavandula sp. extract at the highest concentration, 0.500% insert ignore into journalissuearticles values(w/v);, at the end of the 120 h immersion time. It has been observed that both the surface analysis and EIS findings are very compatible with each other.
