| 中文摘要: |
| 金属铀是一种重要的核材料,在国防工业和能源系统中得到广泛应用,由于其具有高化学活性,当贮存环境中含有微量水蒸气时容易发生腐蚀而影响其使用性能。为深入认识金属铀在含水环境中的腐蚀老化过程,研究人员开展了大量科学研究。围绕腐蚀产物、腐蚀动力学以及腐蚀机理综述了国内外关于金属铀与水反应过程的主要研究成果,从氧化铀缺陷结构、金属铀微观结构对反应过程的影响以及O2的氧化抑制机理等方面对下一步研究方向进行了展望。 |
| 英文摘要: |
| Uranium is one of the most important nuclear material, which have been widely used in defense industry and energy engineering. However, its properties could be decreased due to the reaction with minor vapor existed in the environment during stockpile, which stems from the high chemical reactivity of uranium. A lot of researches are developed in order to recognize the reaction process between uranium and water. The main points of these reactions are reviewed in this paper, including the corrosion pro-ducts, corrosion kinetics and corrosion mechanisms. The future research areas are proposed based on the defect structures in uranium oxide, microstructure of the uranium metal and the inhibition mechanism by oxygen. |
