Abstract

The high-temperature sulfidation of AISI 310 stainless steel coated with Al-7 wt% Si (without or with preoxidation treatment) film was studied over the temperature range 700 - 900°C at 10^-2 - 10^-1 atm sulfur vapor. The Al-Si coating was prepared by hot dipping. The corrosion kinetics followed the parabolic rate law, and the sulfidation rate constants increased with increasing temperature and sulfur pressure in all cases. The scales formed on 310 stainless steel coated with an Al-Si layer consisted of mostly aluminum sulfide (Al₂S₃) and minor amounts of iron sulfide (FeS/Fe_1-xS), chromium sulfides (Cr₂S₃/Cr₃S₄), and (Fe,Ni)₉S₈. The oxides formed on 310 stainless steel coated with an Al-Si layer with preoxidation treatment consisted of mostly α-Al₂O₃, and minor amounts of SiO₂ and Al₂SiO₅. While the scales formed on the alloys without preoxidation treatment consisted of Al₂S₃ and minor amounts of FeS/Fe_1-xS, Cr₂S₃/Cr₃S₄, and (Fe,Ni)₉S₈. The formation of the continuous layers of α-Al₂O₃ and Al₂S₃ was responsible for the reduction of sulfidation rates, and it appeared that α-Al₂O₃ was the best sulfidation-resistant phase among all scales present.
