초록

The corrosion behavior of super austenitic stainless steel was studied by examining the characteristics ofthe sigma phase formed in the steel. A range of experimental and analytical methods was employed, includingpotentiodynamic polarization tests, critical pitting temperature tests, transmission electron microscopy, andenergy-dispersive spectroscopy. Three steel samples with different sigma phase levels were obtained byintentionally adjusting the manufacturing process. The results showed that the corrosion resistance of thesamples was strongly dependent upon the size and distribution of the sigma phase precipitated in the samples. The larger the size of the sigma phase, the higher the Mo content in the sigma phase and the higher thedepletion level of Mo at the interface between the matrix/sigma phase, the more samples with a coarse-sizedsigma phase were susceptible to localized pitting corrosion at the interface. These results suggest that variousmanufacturing processes, such as welding and the post-heat treatment of the steel, should be optimized sothat both the size and fraction of the sigma phase precipitated in the steel are small to improve the resistanceto localized corrosion.
