采用电化学测试和表面分析方法研究了不同电位下形成的钝化膜在含H2S环境中的保护性能和表征。316L在含H2S环境中的耐蚀性随外加电位的增大而降低。俄歇电子能谱（AES）和X射线光电子能谱（XPS）结果表明，Ni参与了钝化膜的形成，并在钝化膜中产生了相应的富集。氧化程度分析表明钝化膜中含有金属元素。在较高的电位下，硫离子在钝化膜中的作用非常明显，这是钝化膜击穿的原因。
The protectiveness and characterization of passive films formed at various potentials in H2S-containing environments were studied using electrochemical measurements and surface analysis method. The corrosion resistance of 316L in H2S-containing environment decreases with the applied potential. The Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) results indicate that Ni participates in the film formation, which results in the corresponding enrichment in the passive film. The oxidization degree analysis indicates that metallic elements are present in the passive film. Sulfide ions are significantly favored in the passive film at higher potentials, which is responsible for the breakdown of passive film.
