金属铀在核能工业领域具有重要应用。铀元素具有活泼的化学性质,极易与环境中的气体、液体甚至固体介质发生反应引起表面腐蚀。金属铀的氢化腐蚀既是关系铀材料长期贮存安全性的实际工程问题,同时也是核材料腐蚀科学研究领域当前最活跃的基础科学问题之一。本文基于铀-氢反应基础及氢化腐蚀的危害,围绕金属铀氢化腐蚀动力学及氢化物形核长大的最新研究进展进行阐述,重点讨论环境因素、材料学因素对铀氢化腐蚀行为的影响。
Progress on Hydrogen Corrosion of Uranium
Uranium plays an important role in the fields of nuclear energy industry.With reactive chemical properties,uranium is easy to react with gases,liquids,and even solid media,leading to surface corrosion.Hydrogen corrosion of uranium is not only a practical engineering problem related to the long-term storage safety of uranium materials,but also one of the most active basic science problems in the field of nuclear material corrosion.In this paper,based on the fundamentals of uranium-hydrogen reaction and the hazards of hydrogen corrosion,the latest progress on the kinetics of hydrogen corrosion of uranium,the nucleation and growth of hydride is elaborated,which focus on the influence of environmental factors and material science factors on the hydrogen corrosion behavior of uranium.
