| Abstract: | The corrosion behavior of Fe-15Ce alloy was studied at 700℃ in H2-CO2, H2-H2S and H2-H2S-CO2 mixtures. Internal oxidation occurs on the Fe-15Ce alloy corroded in H2-CO2 mixtures. The complex scales are formed during the corrosion of the alloy in H2-H2S and H2-H2S-CO2 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 H2-H2S-CO2 is lower than that in H2-H2S, and it is the lowest in H2-CO2. |
