| 中文摘要 | A 200 mum thick Fe-40Al sheet, produced by powder metallurgy and hot extruding, was pie-oxidized at 1373 K in air for different times and then the pre-oxidized specimens were corroded at 1273 K for up to 360 ks in a N-2-11.2 vol.% O-2-7.4 vol.%CO2-500 ppm SO2 atmosphere. The pre-oxidation followed a parabolic rate law, forming continuous, adherent alpha-Al2O3 oxide scales, accompanied by the formation of valley-like flaws. The valley-like flaws originate from the inclusion of additives in the alloy substrate. The inclusion of additives as alpha-Al2O3 in the Fe-40Al sheet leads to some local exfoliation of the oxide scale in the SO2 containing atmosphere. The Fe-40Al pre-oxidized for longer than 14.4 ks showed very good corrosion resistance in the N-2-11.2 vol.% O-2-7.4 vol.% CO2-500 ppm SO2 atmosphere, and there is little exfoliation of the oxide scale after 360 ks oxidation at 1273 K.
