The corrosion behavior of Fe-15Ce alloy was studied at 700 ℃ in H 2-CO 2, H 2-H 2S and H 2-H 2S-CO 2 mixtures. Internal oxidation occurs on the Fe-15Ce alloy corroded in H 2-CO 2 mixtures. The complex scales are formed during the corrosion of the alloy in H 2-H 2S and H 2-H 2S-CO 2 mixtures. No exclusive Ce scales can be founded in any case. This is because of the limited solubility of Ce in the base metal and the presence of intermetallic compounds in the alloy. The corrosion rate of the alloy at 700 ℃ in H 2-H 2S-CO 2 is lower than that in H 2-H 2S, and it is the lowest in H 2-CO 2.
