Abstract

FeCrAl alloy is regarded as the optimization material for coal-gasification purification with high temperature, due to its good mechanical property, oxidation resistance and sulfide resistance. This paper focuses on the effect of preoxidation on sulfidation resistance of porous FeCrAl alloy. The continuous and dense Al2O3 film, which was formed on the surface of porous FeCrAl alloy after preoxidation, can prevent the diffusions of atom S and metal ion and improve the sulfidation resistance.
