Oxidation behavior of Ni3Al and Fe3Al:: I.: XPS calibrations of pure compounds and quantification of the results

Pure oxides of Ni, Fe, and Al were synthesized and analyzed by X-ray photoelectron spectroscopy (XPS) for calibration purposes, as were the spinels NiAl2O4 and FeAl2O4. The quantitative XPS analysis used in further studies to calculate the oxide thickness and the distribution of oxides on the metal surface is described.
