铀及其合金是重要的核材料,其水氧腐蚀研究受到广泛关注。本文系统总结了铀及其合金在真空和大气环境下的氧化反应过程、腐蚀速率和产物,并对不同研究者提出的反应机理进行讨论分析。其中铀-氧反应过程为氧气在表面的吸附、解离,O2-在晶格中进行扩散,O2-在金属和氧化物界面发生反应,其中扩散是反应速率的控制步骤。铀-水体系反应机理存在争议：进行扩散反应的离子是 O2-还是 OH-还没有一致的认识。铀-氧-水体系的反应是氧气和水气共同作用的结果,反应速率介于前两种体系之间。

The reaction of uranium and its alloy with oxygen and water vapor has attracted widely attention as an important nuclear material.The oxidation process,reaction rate and products of uranium and its alloy with oxygen,water vapor and humid oxygen has been sum-marized and discussed.The process of uranium-oxygen systematic reaction includes the adsorption,solution of oxygen on the surface,diffuseness in the crystal lattice which is the determinative step and reaction at the interface of the metal and the oxide.However,the reaction mechanism of uranium-water system was dispersive on the diffuse ion.The uranium-oxygen-water systematic reaction is the result combines the uranium-oxygen and uranium-water reaction.
