摘　　要：钨铜复合材料是由钨和铜复合而成的一种结构功能一体化材料,既具有高的硬度、强度、热稳定性、耐磨性能,还具有低的热膨胀系数、良好的耐烧蚀性能和传导性能,在电子电工、航空航天和武器装备等工业领域得到了广泛应用。商用钨铜复合材料大多通过高温熔渗或液相烧结法制备,具有组织结构粗大,力学性能较低的特点。随着我国工业现代化水平的不断推进,各行各业均得到了迅猛发展,也对钨铜复合材料的综合性能提出了更高的要求。近年来,钨铜粉末及块材制备技术得到了广泛研究,推动了钨铜复合材料的快速发展。本文对钨铜复合材料的多种粉末制备技术和成形技术的原理、特点,以及制备的钨铜复合材料的组织和性能进行了总结和评述,并对钨铜复合材料的未来发展趋势进行了展望。W-Cu composites is a structural and functional integrated material composed of W and Cu,exhibiting exceptional properties such as high hardness,strength,thermal stability,wear resistance,low coefficient of thermal expansion,good ablative resistance and conductivity.It finds extensive applications in electronic,electrical,aerospace and military industries.However,commercial W-Cu composites prepared through high temperature infiltration or liquid phase sintering often possess coarse structures with inferior mechanical properties.As China's industrial modernization progresses rapidly,higher requirements are also put forward for the comprehensive properties of W-Cu composites.As a result,the preparation technology of W-Cu powder and blocks has greatly accelerated the development of W-Cu composites in recent years.This review summarizes the mechanisms and characteristics of different forming technologies and powder preparation techniques for W-Cu composites,along with an analysis of their microstructure and properties.Finally,future trends for the development of W-Cu composites are discussed.
