摘要
通过浸泡试验和腐蚀膜的多重表征，研究了 3Cr 钢和 HP-13Cr 不锈钢（SS）在高温和 CO2 或 H2S 压力环境下的腐蚀行为，并结合 Pourbaix 图和动力学计算进行了分析。在 180 °C/3.8 MPa CO2 条件下，3Cr 钢和 HP-13Cr SS 都表现出双层腐蚀膜，包括外层结晶的 FeCO3 和内层的 Cr2O3 和 Cr(OH)3。此外，在 180 °C/3.8 MPa H2S 条件下，两种钢的腐蚀膜都由外层结晶黄铁矿和黄铁矿层和内层 Cr2O3 和 Cr(OH)3 层组成。由于应力腐蚀开裂的影响，3Cr 在 H2S 中的耐腐蚀性不如 HP-13Cr SS，但与 HP-13Cr SS 在 CO2 中的耐腐蚀性接近。因此，在 CO2 环境中，3Cr 钢可被视为 HP-13Cr SS 的一种经济有效的替代品。
Combining Thermodynamics and Kinetics to Investigate the Corrosion of 3Cr Steel and HP-13Cr Stainless Steel in Extreme Oil-Gas Environments
The corrosion behavior of 3Cr steel and HP-13Cr stainless steel (SS) under high temperature and CO2 or H2S pressure environments was investigated by immersion tests and multiple characterizations of corrosion films, and analyzed by combining the Pourbaix diagram and kinetic calculations. At 180 °C/3.8 MPa CO2, both 3Cr steel and HP-13Cr SS exhibited double-layered corrosion films, comprising a crystalline FeCO3 outer layer and an inner Cr2O3 and Cr(OH)3 layer. Furthermore, at 180 °C/3.8 MPa H2S, the corrosion films of both steels consist of an outer crystalline pyrrhotite and pyrite layer and an inner Cr2O3 and Cr(OH)3 layer. The corrosion resistance of 3Cr in H2S is inferior to that of HP-13Cr SS due to the influence of stress corrosion cracking but is close to that of HP-13Cr SS in CO2. Therefore, 3Cr steel could be considered a cost-effective alternative to HP-13Cr SS in CO2 environments.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
