用电化学阻抗谱（ＥＩＳ）及极化测量，研究了在含ＣＯ２的溶液中Ｃｌ－对ＡＰＩＰ１０５钢的电化学腐蚀行为的影响．结果表明，Ｃｌ－促进了钢铁的阳极溶解，其电化学反应级数为０．７．Ｃｌ－不参与钢铁的阴极反应，在含Ｃｌ－的饱和ＣＯ２溶液中，阴极反应主要为Ｈ２ＣＯ３的去极化反应
Electrochemical impedance spectroscopy (EIS) and polarization measurements were performed to investigate the effect of Cl- on the electrochemical corrosion behavior of APIP105 steel in CO2-containing solutions. The results show that Cl- promotes the anodic dissolution of steel with an electrochemical reaction order of 0.7. Cl- does not participate in the cathode reaction of steel, in a saturated CO2 solution containing Cl-, the cathode reaction is mainly H2CO3 depolarization reaction
