Abstract
The influences of metal cations on the corrosion of mild steel in 10Â mM Clâ aqueous solutions were investigated by electrochemical techniques and immersion tests. Immersion tests and electrochemical impedance spectroscopy (EIS) results showed that Zn2+ has a significant effect on corrosion inhibition. Surface morphological inspection also showed the smooth surface of specimen immersed in Zn2+ containing solution. Analysis of X-ray photoelectron spectroscopy showed that Zn2+ was incorporated in the oxide films by making a strong bond. It is supposed that Zn2+ forms a very effective shielding film which can inhibit the electrochemical reactions, and consequently lowers the corrosion rate.
