摘要
H2S corrosion of 304L and 3161 in oxygen-free Na2SO4 + Na2S solution at pH 3 and temperature of 60 degrees 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 During polarisation H2S Increases significantly the critical current density on 304L and passivation current density i(p) on 316L. Higher i
