Model alloys Fe–20Cr and Fe–20Cr–20Ni, with and without Si additions (0.1, 0.2 and 0.5 wt%), were exposed to Ar–20CO 2 –20H 2 O gas at 818 °C. All undoped alloys underwent breakaway corrosion, resulting in iron-rich oxide scales and internal carbide precipitates. Silicon addition significantly improved both oxidation and carburization resistance in wet CO 2 ...
Model alloys Fe–9Cr, Fe–20Cr and Fe–20Cr–20Ni (wt%) with Si (0.1, 0.2 and 0.5 %) were reacted in Ar–20CO2 gas at 818 °C. Undoped Fe–9Cr formed FeO and FeCr2O4, Fe–20Cr formed only Cr2O3, and Fe–20Cr–20Ni formed Fe3O4, FeCr2O4 and FeNi3. Silicon additions suppressed formation of iron oxides on Fe–9Cr and Fe–20Cr–20Ni, and dramatically slowed oxidation of all alloys. Scales on 0.2Si-alloys consisted...
