摘要
本文通过电化学方法和表面分析研究了 304 不锈钢（SS）在 NaCl 溶液中的被动行为。极化测量结果表明，点蚀电位（Ep）与温度升高呈简单的线性关系。扫描开尔文探针结果表明，304 SS 表面的表面电位差与温度密切相关。扫描电子显微镜结果表明，随着温度的升高，被动膜的破裂速度加快。X 射线光电子能谱分析表明，高温会使 304 SS 表面发生更多氧化，导致更多的 Cr3+ 在高温下被氧化为 Cr6+。
Study on the passive behavior of 304 stainless steel under temperature variation
In this paper, the passive behavior of 304 stainless steel (SS) in NaCl solution is studied by electrochemical methods and surface analysis. The polarization measurement results show that the pitting potential (Ep) has a simple linear relationship with the temperature increase. Scanning Kelvin probe results show that the surface potential difference on the surface of 304 SS is well correlated with the temperature. Scanning electron microscope results show that the rupture of the passive film accelerates with the increase of temperature. The X-ray photoelectron spectroscopy analysis shows that the high temperature causes more oxidation on the surface of 304 SS, leading more Cr3+ oxidized to Cr6+ at high temperature.
