摘　　要：纳米碳/铜复合材料已被视为下一代高性能结构功能一体化铜基材料强有力竞争者,但因纳米碳与铜存在界面润湿性差、界面结合弱等问题导致其强化效率较低。为了改善纳米碳-铜界面结合,研究者们提出了利用与铜、碳均有强润湿作用的WC修饰复合材料界面,并逐渐成为近年来该材料领域研究热点。基于此,本文综述了国内外针对WC修饰纳米碳增强铜基复合材料的制备、微观组织以及性能方面进展,分析了复合材料界面反应和晶体学位向关系,讨论了WC在复合材料强韧化、导电导热等方面发挥的作用,并提出了未来高性能碳化钨修饰的纳米碳/铜复合材料研究重点应从复合材料界面结构对材料性能的影响规律和作用机理、异构组织构型设计等方面开展。Nanocarbon/copper(Cu)composites have been regarded as a strong competitive candidate for the next generation of high-performance Cu matrix materials with structural and functional integration.However,the strengthening efficiency of nanocarbon and Cu is low due to poor interfacial wettability and weak interfacial bonding.To improve the interfacial bonding between nanocarbon and Cu,researchers have proposed the use of the interface of tungsten carbide(WC)-modified composites,which possess strong wettability with both Cu and carbon and has gradually become a research hotspot in this material field.Therefore,this article reviewed the preparation,microstructure,and properties of Cu matrix composites reinforced with WC-modified nanocarbon in China and abroad.The interfacial reactions and crystallographic orientation relationship of the composites were analyzed.The roles of WC in strengthening and toughening,as well as the electrical and thermal conductivity of the composites,were discussed.In addition,it was suggested that future research on high-performance WC-modified nanocarbon/Cu composites should focus on the influence of the interfacial structure on the properties of the composites,the mechanism of action,and the design of heterogeneous structure configuration.
