Abstract

Hot corrosion behavior of two Fe-Cr alloys coated with the salt film of 25 NaCl + 75 Na2SO4 (mass fraction) in air at 1173 K was studied. Results show that for both alloys of Fe-10Cr and Fe-20Cr, the mass gain of the alloy coated with 40–45 g/m2 of 75 Na2SO4 + 25 NaCl is greater than that of the alloy coated with 20–25 g/m2 of the film with the same composition. The corrosion products of Fe-10Cr alloy can be divided into three layers, of which the outermost scale is Fe2O3, the intermediate layer is mixed oxides of Fe2O3 and Cr2O3, and the innermost layer is mainly chromium sulfide. However, the corrosion products of Fe-20Cr only consist of two layers: the external scale of Fe2O3 and Cr2O3, and the internal layer of chromium sulfide. Compared to Fe-10Cr, Fe-20Cr has better hot corrosion resistance. The hot corrosion mechanism was proposed and the influence of the different coating mass of 75 Na2SO4 + 25 NaCl is also discussed.

Keywords: Hot corrosion; Fe–Cr alloy; 75 Na2SO4 + 25 NaCl
