    摘要:

    近年来,纳米石墨烯在摩擦学领域引起了一番新的热潮,纳米石墨烯因具有独特的物化性能、超薄层间结构和优良的自润滑性能,将其作为润滑添加剂能够显著提高机体的摩擦学性能。文中综述了纳米石墨烯作为固体润滑剂、水基润滑添加剂和油基润滑添加剂以及与其他纳米粒子的复合材料作为润滑添加剂的研究进展,归纳总结了石墨烯的保护层薄膜、低表面能、自润滑性能、复合材料共同作用等减摩抗磨机理;指出了纳米石墨烯存在的问题,如不同添加量的石墨烯对溶液的抗磨减摩影响较大,石墨烯的层数和结构都是影响机体抗磨减摩的重要因素,并对今后石墨烯的研究方向进行了展望。

    Abstract:

    In recent years, nano-graphene has caused a new upsurge in the field of tribology. Graphene has unique physical and chemical properties, ultra-thin interlayer structure and excellent self-lubricating properties. As a lubricating additive, graphene can significantly improve the tribological properties of the body. In this paper, the research progress of nano-graphene as solid lubricant, water-based lubricating additive and oil-based lubricating additive and composite with other nanoparticles as lubricating additive is reviewed. the anti-friction and antiwear mechanisms of graphene, such as protective film, low surface energy, self-lubrication and composite materials are summarized. The problems existing in nano-graphene are pointed out, for example, different amounts of graphene have great influence on the anti-wear and friction reduction of the solution, and the layer number and structure of graphene are important factors affecting the anti-wear and friction reduction of the body. The future research direction of graphene is prospected.
