The oxidation behavior of an equimolar FeCoNiCrMn high-entropy alloy was studied in various CO/CO2 mixed gases over the oxygen partial pressure range from 5.03 10-16 to 5.03 10-14 Pa at 973K (700oC). The results showed that the oxidation kinetics of the alloy followed the parabolic rate law, regardless of oxygen pressure. The oxidation rate constants increased with increasing oxygen partial pressure, indicative of a typical oxide scale exhibiting a p-type semiconductivity. The scales formed on the alloy consisted mostly of MnO and minor amount of (Mn,Cr)3O4.
