Abstract
Abstract The corrosion behaviors of as-cast Fe-5Cr-5Si alloy with and without sputtered Fe-5Cr-5Si film in H 2 -CO 2 -H 2 S 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 + FeCr 2 O 4 + Fe 2 SiO 4 inner layer. However, a continuous Cr 2 O 3 + SiO 2 layer which possesses favorable protectiveness forms at the coating/alloy interface for the coated alloy, even though FeS layer and FeS + FeCr 2 O 4 + Fe 2 SiO 4 mixed layer also form. The formation mechanism of the Cr 2 O 3 + SiO 2 layer on the coated alloy is discussed thoroughly.
