摘　　要：铜基复合材料(Cu-MMCs)因其优异的力学性能和耐磨性,广泛应用于高速列车刹车片等摩擦材料的研究.然而,随着高速列车运行速度的提升,铜基复合材料在应急制动过程中由于热稳定性不足,面临较大的挑战.通过加入陶瓷组元,可以显著改善铜基复合材料的摩擦系数,并通过灵活调整多种陶瓷组元的组成、含量和粒度,能够显著提升其在高温下的力学和摩擦性能.本文中综述了不同类型和不同数量陶瓷组元增强铜基复合材料的强化效果及其影响机制,涵盖了单组元、双组元及多组元陶瓷的研究进展.文章中探讨了不同陶瓷组元的制备方法、类型及陶瓷含量对铜基复合材料的力学、热学和摩擦学性能的影响.通过总结大量研究者的工作,本文中比较了不同陶瓷对铜基复合材料摩擦机制的改变.这项工作有望能为未来陶瓷增强铜基复合材料的研究和应用提供有价值的参考.Copper-based materials(Cu-MMCs)have been widely researched for use as friction materials in applications like high-speed train braking pads due to their superior mechanical properties and wear resistance.However,as the operating speeds of high-speed trains increasing,Cu-MMCs are finding it challenging to meet the demands of emergency braking due to inadequate thermal stability.The incorporation of ceramic components can substantially improve the friction coefficient of Cu-MMCs,and by flexibly adjusting the composition,content and size of multiple ceramic types,their mechanical and frictional properties at elevated temperatures can be significantly enhanced.This review focuses on the enhancement effects and influencing mechanisms of Cu-MMCs reinforced with different types and quantities of ceramic components,including single,dual,and multi-component ceramics.This study examines various preparation methods,types of ceramics,and the effects of ceramic content on the mechanical,thermal,and tribological properties of Cu-MMCs.By summarizing the extensive work of numerous researchers,this review compares how different ceramics alter the friction mechanisms of Cu-MMCs.The authors hope that this work provides valuable insights for the future development of ceramic-reinforced Cu-MMCs composites with superior properties.
