核环境下的摩擦、磨损与润滑

理解核环境下材料的摩擦、磨损与润滑问题对建设商用第三代核反应堆、发展新型四代堆以及验证未来先进聚变核能系统至关重要. 服役于核岛尤其是核反应堆一回路的机械部件及材料，不仅承受运动过程中循环应力及摩擦磨损，而且还要面对高温、腐蚀和辐射等极端环境，本文中针对反应堆中核环境下结构材料摩擦磨损问题，以及核环境下润滑材料特殊需求，总结了本领域研究进展及面临的挑战，并对推进及解决核环境下材料的摩擦、磨损与润滑研究提出了展望. 

Friction,Wear and Lubrication in Nuclear Environments

Understanding the friction, wear and lubrication of materials used in nuclear environments is important to build the third and fourth generation nuclear fission reactor, and also a critical factor to prove the feasibility of future advanced nuclear fusion reactor. Materials worked in mechanical component of reactor especially in the primary circuit not only suffer to cyclic stress, friction and wear, but also directly face high temperature, erosion and radiation harsh environments, in this review the friction and wear of structural materials, as well as the unique requirement of lubricants used in nuclear reactor were discussed, the progress and challenge in this research field were also summarized and proposed.
