研究领域：碳钢腐蚀 测量方法：塔菲尔曲线和交流阻抗 100kHz - 0.1Hz H2S corrosion of 304L and 316L in oxygen-free Na2SO4 + Na2S solution at pH 3 and temperature of 60 C were investigated by EIS, potentiodynamic polarisation, multi-component Pourbaix diagrams and microstructure characterization. At similar conditions, lower corrosion rate was observed on 316L, attributed to its denser (1.5 times) and smoother (6%) surface layer and confirmed by SEM micrograph.
