Melia Azedarach (TAE) extract was investigated as eco-friendly corrosion inhibitors of mild steel in 1.0 M HCl using potentiodynamic polarization, linear polarization resistance, electrochemical impedance spectroscopy (EIS), scanning electron microscopy and atomic force microscopy techniques. The experimental results show that TAE is good corrosion inhibitor and the inhibition efficiency is increased with TAE extract concentrations. The results of AC impedance have shown that polarization resistance increased and constant phase element decreased with increasing TAE concentrations. Polarization curves indicated that TAE is mixed inhibitor. Scanning electron and atomic force microscopy studies confirmed the formation of a protective film on the mild steel surface. The inhibitor adsorbed on the iron surface was found to be in a good agreement with the Langmuir adsorption isotherm and the value of adsorption free energy of (G°ads) was also calculated
