摘要
应用动电位扫描和电化学阻抗谱研究了Cl-对N80钢在CO2水溶液中腐蚀行为的影响.结果表明:随着介质中Cl-浓度的增加,基体的阳极溶解速率先增加后减小;而阴极的还原速率则缓慢减小.
The Effect of chloride ion on electrochemical behavior of N80 steel in CO2 saturated solutions were examined by potentiodanymic and electrochemical impedance spectroscopy (EIS). The results showed that increasing NaCl content in the solution, the anodic dissolution rate of N80 steel in CO2 saturated solution increased firstly, and then decreased. While for the cathodic reaction rate, it slowly decreased with increasing NaCl content in the solution.
