摘　　要：固体润滑薄膜以其优异的减摩抗磨性能、化学稳定性和高温稳定性在航空航天、核工业及机械制造等领域得到广泛应用。然而,在太空、核反应堆等极端环境中,固体润滑薄膜易受辐照损伤而导致润滑性能失效。本文首先介绍了3类常用的固体润滑薄膜:二维层状润滑薄膜、碳基润滑薄膜和金属基润滑薄膜,并概述了它们在辐照和摩擦学方面的研究进展。然后,提出了该领域目前存在的问题,并总结了该领域未来的发展方向。最后,针对固体润滑薄膜在辐照环境下面临的挑战,从热退火处理、元素掺杂、多层复合膜结构设计、界面调控、晶粒细化5方面展望了提高3类常用的固体润滑薄膜抗辐照性能的措施。该综述旨在帮助研究人员了解该领域研究的重要性及紧迫性,以推动具有优异抗辐照性能的固体润滑材料在苛刻辐照领域的发展应用,从而确保其机械部件在极端环境下的可靠性和稳定性.Solid lubricating thin film materials play a significant role in aerospace,the nuclear industry and mechanical engineering due to their excellent performance in reducing friction and wear,as well as their good chemical stability and resistance to high temperatures.However,these materials face the challenge of radiation damage in extreme environments,such as space and high-temperature nuclear reactors,which can lead to a significant decrease in material performance,thus affecting their reliability and durability in practical applications.In this paper,three main types of solid lubricating thin films were first introduced,which included two-dimensional layered lubricating films,carbon-based lubricating thin films,and metal-based lubricating thin films.Two-dimensional layered lubricating films,such as graphene and transition metal dichalcogenides,showed ultra-low friction coefficients due to their single or few layers of atomic thickness,achieving a“superlubricating”effect.These materials were not only recognized for their excellent tribological properties but also for their exceptional mechanical strength and chemical inertness,making them potentially valuable for applications in harsh environments,such as nuclear radiation.Carbon-based lubrica-ting thin films,such as hydrogenated amorphous carbon films,graphite,and fullerenes,maintained their lubricating performance in adverse environments due to their diverse allotropes of carbon and physical and chemical properties.Metal-based lubricating thin films,especially silver-based films,were shown to exhibit good lubricating performance in high-temperature and irradiation environments when combined with other solid lubricants.Secondly,the challenges faced by solid lubricating films in irradiation environments were summarized,and an outlook on future research directions in the field of radiation resistance of commonly used solid lubricating films was provided.Five strategies to enhance the radiation resistance of solid lubricating films were further explored:First,th
