Isothermal oxidation behavior of chromium with and without nanometric sol–gel CeO 2 coating is studied at 1000°C in air. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) are used to examine the surface morphology and microstructure of their oxide films. It is found that ceria coating greatly improves the anti-oxidation property of chromium. Laser Raman spectrometer...
