采用动电位极化和阻抗法研究了温度对13cr马氏体不锈钢在co2和Cl−环境中的钝化行为和耐蚀性的影响。不同的样品在暴露于90、120和150°C时进行测试。根据极化曲线确定反应机理。表面膜的特性是由阻抗传递函数模型确定的，它涉及金属/钝化膜上发生的反应以及扩散过程。有关系统电化学参数的信息被用来解释温度对钝化膜和耐蚀性的影响。这些结果与SEM和XPS分析一致。
Potentiodynamic polarization and impedance measurements are used to examine the effects of temperature on the passivation behavior and corrosion resistance of 13 Cr martensitic stainless steel in CO2and Cl−environment. Different specimens are tested during exposure to 90, 120 and 150 °C. Reaction mechanisms are decided from polarization curves. The characteristics of the surface film are determined from impedance transfer function model, which involve the reactions occurring at the metal/passive film as well as diffusion processes. Information concerning system electrochemical parameters is used to interpret the effects of temperature on the passive film and corrosion resistance. These results are consistent with the SEM and XPS analysis.
