采用动电位曲线和电化学阻抗谱（EIS）研究了HP 13 Cr 110不锈钢在模拟地层水中的CO2腐蚀行为;采用扫描电镜（SEM）、X射线衍射（XRD）和X射线光电子能谱（XPS）分析了高温高压下形成的腐蚀产物膜的微观结构和成分。结果表明，13 Cr不锈钢在地层水中处于钝化状态，随着温度的升高，钝化电流密度增大，钝化电位区减小。高温高压下形成的腐蚀产物膜主要由铁铬氧化物和少量FeCO 3组成。
The carbon dioxide corrosion behaviour of HP13Cr110 stainless steel in simulated stratum water is studied by potentiodynamic curve and electrochemical impedance spectroscopy (EIS); the micro-structure and composition of the corrosion scale formed at high-temperature and high-pressure are analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). The results show that 13Cr stainless steel is in passive state in the stratum water, the passive current density increases and the passive potential region decreases with increasing temperature. The corrosion scale formed at high-temperature and high-pressure is mainly composed of iron/chromium oxides and a little amount of FeCO3.
