Abstract

Graphene-incorporated ceramics are recognized as promising candidates for various tribological applications, including machining tools, nozzles, mechanical seals, bearings, and gears. Generally, graphene-incorporated ceramics exhibit lower friction coefficients and wear rates compared to ceramic composites reinforced by other lubricants, including CaF₅, MoS₂, h-BN, carbon fiber, and CNTs. This review comprehensively summarizes the current knowledge of the tribological performance of graphene-reinforced ceramics, highlighting the effects of in situ grown graphene, core-shell structured graphene, three-dimensional assembled graphene, and functionally graded graphene on the friction and wear properties of ceramics. In situ graphene forms stable lubrication films, effectively reducing the friction coefficient of the ceramic matrix. Core-shell structured graphene ceramics achieve outstanding wear resistance through rolling friction mechanisms and crack inhibition. Three-dimensional assembled graphene enhances the stability of lubrication films and contributes to superior friction reduction. Functionally graded graphene ceramics optimize internal structures, improving impact resistance and tribological stability. Furthermore, the challenges and future development directions of graphene-incorporated ceramics are discussed, highlighting their promising applications in high-temperature, extreme environments, and precision mechanical systems.

石墨烯增强陶瓷的摩擦学性能

石墨烯陶瓷被认为是各种摩擦学应用的有前途的候选者，包括加工工具，喷嘴，机械密封，轴承和齿轮。通常，与其他润滑剂（包括CaF5、MoS2、h-BN、碳纤维和CNTs）增强的陶瓷复合材料相比，石墨烯陶瓷具有更低的摩擦系数和磨损率。本文综述了石墨烯增强陶瓷摩擦学性能的研究现状，重点介绍了原位生长石墨烯、核壳结构石墨烯、三维组装石墨烯和功能梯度石墨烯对陶瓷摩擦磨损性能的影响。石墨烯在原位形成稳定的润滑膜，有效降低陶瓷基体的摩擦系数。核壳结构石墨烯陶瓷通过滚动摩擦机制和裂纹抑制实现了优异的耐磨性。三维组装的石墨烯增强了润滑膜的稳定性，并有助于减少摩擦。功能梯度石墨烯陶瓷优化了内部结构，提高了抗冲击性和摩擦学稳定性。此外，还讨论了石墨烯陶瓷面临的挑战和未来的发展方向，重点介绍了其在高温、极端环境和精密机械系统中的应用前景。
