| 中文摘要: |
| 目的 研究 316L 不锈钢在碱性硫化物溶液中的应力腐蚀行为,为其在碱性环境中的适用性提供参考依据。 方法 采用动电位极化曲线、电化学阻抗(EIS)测量技术、慢应变速率拉伸试验(SSRT)、U形弯试样浸泡试验以及 SEM 腐蚀形貌分析方法。 结果 316L 不锈钢试样在碱性硫化物溶液中具有较低的应力腐蚀(SCC)敏感性,腐蚀机理主要为阳极溶解型,且 SCC 敏感性随着 pH 升高而降低。 结论316L 不锈钢试样在碱性 NaCl/ Na2S 溶液中虽然表现出应力腐蚀特征,但敏感性较低,适用于该实验模拟的碱性溶液中。 |

| Objective To study the stress corrosion cracking (SCC) behavior of 316L stainless steel in alkaline sulphide solution, and to provide reference for its applicability in alkaline environment. Methods Potentiodynamic polarization, electrochemical impedance spectrums (EIS), slow strain rate test(SSRT), U type bending immersion test and superficial analysis technique using scanning electron microscope (SEM) were applied. Results 316L stainless steel had relatively low SCC susceptibility in alkaline sulphide solution, and the main corrosion mechanism was anodic dissolution (AD). The SCC susceptibility decreased with the increase of pH value. Conclusion Although 316L stainless steel showed features of stress corrosion in alkaline NaCl/ Na2S solution, the SCC sensitivity was low, so it was suitable for the simulated alkaline solution in the experiment. |
