The Effects of Ferula (Ferula elaeochytris K.) to Electrochemical Behaviour of Mild Steel in Chloride Medium

In this study, the effect of Ferula in the electrochemical behaviour of mild steel has been investigated in 3.5% NaCl solution (pH=8.5) using electrochemical impedance spectroscopy (EIS). Nyquist and Bode diagrams were obtained in different concentrations of Ferula. The surface morphology of the mild steel was examined by scanning electron microscopy. The obtained results show that, Ferula inhibits corrosion of mild steel in 3.5% NaCl solution. It has been found that the efficiency of the inhibition is changed by the concentration of the Ferula extract
