Hot Corrosion of Inconel 740 Alloys in Na2SO4-NaCl Salts

The Ni-Cr-Co based superalloy, Inconel 740, was corroded between 700 and 900°C for 20 h in 75% Na2SO4-25% NaCl salt. The scale consisted primarily of Cr2O3, (Ni,Co)Cr2O4, NiO, and Ni3S2. During corrosion, oxidation dominated rather than sulfidation. The scale was neither dense nor compact owing to the formation of the (oxides, sulfides)-mixed scale where Na2SO4and NaCl were incoporated.
