Increase of oxygen permeability on metal/oxide interface during high temperature oxidation of Fe-Cr alloys in water vapor at 1073 K

Increase of oxygen permeability on metal/oxide interface during high temperature oxidation of Fe-Cr alloys in water vapor at 1073 K

Many studies1-3 have shown that oxidation rates in humid environment are higher than in dry environment. The formation of Cr2O3 scale during high temperature oxidation is beneficial in protecting metals from severe oxidizing environment. A dilute solid solution, such as Fe-Cr alloy with small Cr con...
