【Abstract】 The studing for the surface oxidation of uranium and oxide by X-ray photo-electron spectroscopy (XPS) , Auger electron spectroscopy (AES) , secondary ion mass spectroscopy (SIMS) , and the surface oxidation of uranium in different gaseous atmospheres such as O2, H2, CO, CO2, H2O (v) and air were reviewed. The surface oxidation of uranium is greatly influenced by a number of parameters including atmospheric temperature, pressure, diffusion of adsorded gas atoms through the oxide layer, surface and interface chemical component, and defect structure and electron nature of the oxide layer. The initial oxidation mechanism and kinetics have been discussed. Suggestions for future work have also been presented.更多还原
