“…Many studies have shown that oxidation rates in humid environment are relatively higher than in dry environment. [2][3][4][5][6] A possible mechanism is that water vapor retards the formation of protective scale. Extensive works have been done to understand the role of water vapor in impeding the formation of protective Cr 2 O 3 scale, but the explanations remain in qualitative manner.…”

“…However, Cr 2 O 3 might be unstable above 1050°C due to its conversion to chromium carbides 1,2 or volatile CrO 3 . 7,8 Another disadvantage is that protective Cr 2 O 3 cannot be formed in highly-reducing, carburizing atmospheres, such as CH 4 -H 2 . Novel Fe-base or Ni-base alloys are often alloyed with Al or Si.…”

The cyclic carburization of electrodeposited pure and CeO 2 -dispersed Ni 3 Al intermetallic coatings on Fe-Ni-Cr alloys has been investigated at 850 and 1050°C for periods up to 500 h in a reducing 2%CH 4 -H 2 atmosphere. At 850°C, all Ni 3 Al-base-coating samples showed excellent carburization resistance and slow mass increases due to the formation of a thin c-Al 2 O 3 scale and a low carbon activity (a c = 0.73). At 1050°C and a high carbon activity (a c = 3.21), all coatings are superior to the uncoated Fe-Ni-Cr alloy in terms of carburization resistance. A thin a-Al 2 O 3 scale slowly formed on all Ni 3 Al coatings effectively blocked the carbon attack. The addition of CeO 2 particles in the Ni 3 Al coatings significantly mitigated the cracking of the a-Al 2 O 3 scale and the resultant internal oxidation and carburization. For all coatings, Ni-rich particles were found to be formed on the a-Al 2 O 3 scale during oxidation, which had led to the deposition of catalytic coke.
