Research Progress on Surface Corrosion of Uranium Materials

Abstract

In order to understand the oxidation and corrosion mechanism of uranium and its compounds surface and explore the environmental system that can effectively alleviate the oxidation and corrosion of uranium materials, this paper reviews the research on the surface chemistry of uranium and its compounds at home and abroad, the adsorption behaviors of reactive gases such as H2, O2, CO, CO2 and inert gases such as N2 on different surfaces of uranium and its compounds were compared and analyzed, which deepens the understanding of the corrosion behavior of uranium and its compounds in the air, and gets some useful conclusions; this paper concludes that the interaction between U and various gases is accompanied by the transfer of charges, the main mechanism of action is that the different hybrid orbitals of gas atoms and U7s, U6d, U5f and other hybrid orbitals interact to form new chemical bonds, which led to related reactions and phenomena; in this paper, the research on surface corrosion of uranium and its compounds is also prospected from three aspects: improving the research methods, carrying out the study of different surface adsorption behaviors of different phases of uranium atoms, and exploring new systems for protecting uranium materials from oxidation and corrosion.
