Uranium as an important energy material plays a significant role in the national econ my and national defense. However, uranium metal is very active, and it is very easy to be oxidized and corroded in the environment. The corrosion not only leads to the nuclear pollution of environment, but also leads to the deterioration or failure of its components performance. Therefore, it is very important to study the corrosion and oxidation behavior of uranium metal and to find the appropriate an-ti-corrosion treatment technology, which has important scientific research value and great engineering significance. This report will briefly introduce the recent research progress on the corrosion behavior of uranium metal and the preparation and properties of nitride layer on uranium metal surface.It is an important foundation for the design of effective anti-corrosion technology to understand how the metal is oxidized in the environment. In view of the nitriding technology in Ti and Fe-based alloys, the successful application to improve the surface wear resistance and corrosion resistance, the research group has explored ion implantation, laser surface nitriding and glow plasma nitriding tech-nology to prepare various uranium nitrides on uranium surface. The relationship between the prepara-tion technology and the composition as well as structure of the surface layer was studied. By using tran mission electron microscopy (TEM), Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS), it is found that surface nitriding can effectively improve the corrosion resistance of the metal uranium, and the nitride with high nitrogen content exhibits better oxidation resistance than the one with low nitrogen content. In addition, the first principle calculation reveals that the anti-oxidant corrosion mechanism is mainly due to the uranium nitride has changed the adsorption and dissociation behavior of O2 on its surface. The transport of dissociated ions to nitride lattice is hindered, so as to the nitride / metal interface caused by continuous oxidation is prevented. Another interesting finding is that although the nitride thermodyn mically is easily oxidized, but once oxygen ions enter in the lattice of the nitride with high nitrogen content, a more stable structure than nitride can be formed (Oxynitride or Oxygen contained nitride). It can prevent the occurrence of further oxidation corrosion. These findings will contribute to the development of metal uranium surface corrosion protection technology.
