  • 摘要: 随着现代工业对极端工况下润滑材料需求的日益增长,传统金属基和有机润滑材料在高温、高负荷和强腐蚀等恶劣环境中的性能瓶颈日益凸显. 陶瓷润滑技术作为1种先进的润滑技术,能够有效实现高温和腐蚀等苛刻环境下的润滑与密封. 陶瓷润滑材料因其具有耐高温、耐腐蚀和低密度等诸多优点,在航空、航天、兵器以及船舶等高端装备技术领域也展现出了广泛的应用前景和重要价值. 然而,陶瓷材料作为润滑材料在干摩擦条件下的摩擦系数和磨损率都比较高,极大地制约了高性能陶瓷润滑材料在高端装备技术领域的应用. 因此,如何对陶瓷润滑材料开展组分和结构设计,实现结构/润滑功能一体化,是当今固体润滑材料领域的研究热点和重点. 本文中主要综述了近年来高性能陶瓷润滑材料的研究进展,重点探讨了通过常规摩擦学设计、新型结构设计(包括多孔结构、仿生结构、功能梯度结构以及表面织构化设计)和高熵陶瓷材料设计研究陶瓷润滑材料的摩擦学性能,以及各类设计参数对摩擦学性能的影响规律,并对高性能陶瓷润滑材料未来研究方向进行了展望,以期指导高性能陶瓷润滑材料的设计和推动其在高端技术装备中的应用.

     

    Abstract: With the increasing demand for lubricating materials under extreme working conditions in modern industry, the performance limitations of traditional metal-based and organic lubricating materials in harsh environments, such as high temperature, high load, and strong corrosion, are becoming increasingly evident. Ceramic lubrication technology, recognized as an advanced lubrication approach can effectively facilitates lubrication and sealing in extreme conditions, including high temperatures and corrosive environments. Ceramic lubricating materials demonstrate significant application potential and value in high-end technology sectors, such as aviation, aerospace, military applications, and maritime industries, owing to their advantages, including high-temperature resistance, corrosion resistance and low density. However, ceramic materials exhibit relatively high friction coefficients and wear rates under dry friction, which significantly restricts the applicability of high-performance ceramic lubricating materials in the field of high-end equipment technology. Consequently, the design of components and structures for ceramic lubricating materials, aimed at integrating structural and lubrication function, has emerged as a key research focus in the domain of solid lubricating materials. This article primarily summarized recent advances in high-performance ceramic lubricating materials, emphasizing the investigation of their tribological properties through conventional tribological design, novel structural design (including porous structures, biomimetic structures, functional gradient structures and surface texturing design) and high-entropy ceramic material design. Additionally, the impact of various design parameters on tribological properties was discussed. Future research directions for high-performance ceramic lubricating materials were also explored to guide the design process and enhance their application in high-end technical equipment.
