The oxidation kinetics of the alloy followed the parabolic rate law, and the oxidation rate constants increased with increasing oxygen partial pressure. Triplex scales formed on the alloy consisted of an exclusive outer layer of Mn3O4, a heterophasic intermediate layer of Mn3O4, (Mn,Cr)3O4, and Cr2O3, and an exclusive inner layer of Cr2O3. |
