Abstract

The corrosion behaviors of as-cast Fe-5Cr-5Si alloy with and without sputtered Fe-5Cr-5Si film in H₂-CO₂-H₂S mixture at 700 °C are studied. The corrosion scale forming on the as-cast alloy is non-protective and mainly composed of FeS outer layer and FeS + FeCr₂O₄ + Fe₂SiO₄ inner layer. However, a continuous Cr₂O₃ + SiO₂ layer which possesses favorable protectiveness forms at the coating/alloy interface for the coated alloy, even though FeS layer and FeS + FeCr₂O₄ + Fe₂SiO₄ mixed layer also form. The formation mechanism of the Cr₂O₃ + SiO₂ layer on the coated alloy is discussed thoroughly.
