X80钢的CO2腐蚀电化学行为与机理研究
Electrochemical Corrosion Behavior and Mechanism of X80 Steel in the Aqueous Solution of Carbon Dioxide
摘 要
在模拟油田采出水腐蚀环境中, 采用电化学交流阻抗和动电位扫描极化曲线测试技术, 研究了X80钢在温度为60 ℃, 饱和CO2条件下的腐蚀电化学行为和阳极与阴极的反应机理, 实时监测了腐蚀产物膜对腐蚀行为和腐蚀反应机理的影响。研究结果表明: X80钢的阳极反应过程服从Bockris机理; X80钢的阴极反应以H2CO3的还原为主; 反应中间产物吸附与腐蚀产物膜覆盖的竞争导致交流阻抗谱随腐蚀时间而变化, 影响着钢的腐蚀行为;产物膜对钢基体具有一定的保护作用。

Abstract
The corrosion environment in oil produced water was simulated in the solution saturated with CO2, and the electrochemical corrosion behavior of X80 steel and the reaction mechanisms in anode and cathode at 60 ℃ were studied by means of electrochemical impendence spectroscopy(EIS) and potentialydynamic polarization curve. The effects of corrosion product film on the corrosion behavior and the corrosion reaction mechanism were monitored. The results showed that the anodic reactions obey Bockris mechanism, the predominant cathodic reaction is the reduction of carbonic acid, the competition between the deposition of corrosion product and the adsorption of reaction intermediate product influences the corrosion behavior of X80 steel and leads to the variation of EIS with corrosion time. The corrosion product film prevents X80 steel from further corrosion.
