N2 - The oxidation behavior of a nickel-based single crystal superalloy at 1100 °C under three different oxygen concentrations (10%/21%/30%) was studied. The results showed that the ambient oxygen concentrations had a significant effect on the oxidation rate and oxide layered structures of the tested alloy. With the increase of oxygen concentration, the oxidation rate of the test alloy increased significantly, and the parabolic oxidation rate constants obtained by fitting had a linear relationship with the oxygen concentrations. At 10% and 21% oxygen concentration, Al2O3 was formed on the sample surfaces with the increase of oxidation time, while at 30% oxygen concentration, a typical three-layer oxide layered structure—outer (Ni, Co)O, middle complex oxides with spinel phase structure, and inner Al2O3—was formed. In addition, the causes of oxide scale spalling, the influence of oxygen concentrations on different oxide layered structures, and the oxidation mechanism based on ionic diffusion were discussed in detail.
