Abstract The influences of metal cations on the corrosion of mild steel in 10 mM Cl − aqueous solutions were investigated by electrochemical techniques and immersion tests. Immersion tests and electrochemical impedance spectroscopy (EIS) results showed that Zn 2+ has a significant effect on corrosion inhibition. Surface morphological inspection also showed the smooth surface of specimen immersed in Zn 2+ containing solution. Analysis of X-ray photoelectron spectroscopy showed that Zn 2+ was incorporated in the oxide films by making a strong bond. It is supposed that Zn 2+ forms a very effective shielding film which can inhibit the electrochemical reactions, and consequently lowers the corrosion rate.

金属阳离子在 10 mM Cl - 水溶液中对低碳钢腐蚀的影响

摘要 通过电化学技术和浸泡试验研究了金属阳离子对10 mM Cl - 水溶液中低碳钢腐蚀的影响。浸泡试验和电化学阻抗谱（EIS）结果表明，Zn 2+ 对缓蚀有显着影响。表面形态检查还显示浸入含 Zn 2+ 溶液的试样表面光滑。X 射线光电子能谱分析表明，Zn 2+ 通过形成强键结合到氧化膜中。据推测，Zn 2+ 形成了非常有效的屏蔽膜，可以抑制电化学反应，从而降低腐蚀速率。
