摘要：

Model alloys Fe-9Cr, Fe-20Cr and Fe-20Cr-20Ni (wt.%) with Ce (0.05%, 0.1%) or Mn (1%, 2%) were exposed to Ar-200O(2) gas at 818 degrees C. Scales on Fe-9Cr alloys consisted of FeO and FeCr2O4, Fe-20Cr-(Ce) alloys formed only Cr2O3, and Fe-20Cr-(Mn) alloys formed Cr2O3 and MnCr2O4. All Fe-20Cr-20Ni alloys formed Fe3O4, FeCr2O4 and FeNi3. Cerium additions had little effects, but additions of 2% Mn significantly improved oxidation resistance of Fe-20Cr and Fe-20Cr-20Ni alloys. Most alloys also carburized. All alloys developed protective chromium-rich oxide scales in air. Different behavior in the two gases is attributed to faster Cr2O3 scaling rates induced by CO2. (C) 2013 Elsevier Ltd.
