Effect of Fe on the oxidation, sulfidation and carburization behaviors of alloys in CO2 containing SO2
Source abstract
Abstract
The effect of Fe on the oxidation, sulfidation and carburization behaviors of alloys in CO 2 containing SO 2 at 1000 ℃ was investigated using multiple evaluation methods, including first-principles, molecular dynamics simulation, high-temperature corrosion experiment and thermodynamic analysis. The adsorption capacity of both gas molecules on FeCr alloy surface was stronger than that on NiCr alloy surface. The molar content of O, C and S atoms in Fe-25Ni-22Cr alloy was higher than that in Ni-25Fe-22Cr alloy. The increase of Fe content promoted the reactions between alloy elements and O, C, S atoms, which caused serious corrosion of Fe-Ni-Cr alloys.
