核壳型纳米复合材料的润滑作用及机理研究进展

Research Progress on Lubrication Mechanism of Core-Shell Nanocomposites

摩擦磨损一直是能源消耗和材料损耗的主要原因。而润滑油添加剂作为现代润滑油的必要组分,对润滑油性能起着至关重要的作用。碳基材料是一种高效的环保型润滑油添加剂,因其具有高强度、优良的耐磨性、耐化学性等特性,可有效提高润滑油的摩擦学性能,被广泛应用于各种场景。核壳纳米材料由“芯体”和“壳层”两部分组成,在润滑性能方面,核壳纳米材料既可以发挥二者的互补作用,形成协同润滑机制,又可以根据润滑场景的需要,有目的性地设计“芯体”和“壳层”,使其分别具有支撑-润滑作用或修补-保护作用,成为性能优异的润滑组分,具有较好的研究和应用前景。对核壳型纳米复合材料作为纳米润滑添加剂的研究进展进行综述,归纳总结近期核壳型纳米复合材料支撑三种重要润滑机理的研究成果,为相关研究提供重要的进展研究综述成果。

Friction and wear has been a major cause of energy consumption and material loss.As a necessary component of modern lubricating oil,lubricating oil additives play a crucial role in the performance of lubricating oil.Carbon-based material is an efficient and environmentally friendly lubricant additive.Because of its high strength,excellent wear resistance,chemical resistance and other characteristics,it can effectively improve the tribological properties of lubricating oil,and is widely used in various scenarios.Core-shell nanomaterials are composed of two parts:"core"and"shell".In terms of lubrication performance,core-shell nanomaterials can not only play the complementary role of the two to form a collaborative lubrication mechanism,but also purposefully design"core"and"shell"according to the needs of lubrication scenes,so that they have the functions of support-lubrication or repair-protection respectively.It is an excellent lubricating component and has a good research and application prospect.In this paper,the research progress of core-shell nanocomposites as nano-lubricating additives is reviewed,and the recent research results on three important lubrication mechanisms supported by core-shell nanocomposites are summarized to provide important progress and review results for related research.
