Cl-对API P105钢在含CO2溶液中的电化学腐蚀行为的影响
Influence of Cl - on Corrosion Behavior of API P105 Steel in the CO 2 Saturated Solution
【摘要】 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
【Abstract】 Corrosion mechanism for API P105 steel in the CO 2 saturated solution with Cl - was studied by using electrochemical impedance spectroscopy(EIS) and polarization measurements. The results showed that Cl - promoted the dissolution of iron, and the order of the electrochemical reaction was 0 7, Cl - did not take part in the cathodic reaction, the main cathodic reaction was controlled by the depolarization reaction of H 2CO 3.
