摘　　要：高导电导热性铜与高温强度、强抗电弧烧蚀钨的良好结合使钨铜复合材料具有一系列优异性能。钨与铜的互不相溶性决定了钨铜复合材料制备的特殊性。由于纳米颗粒具有特殊性能和很大的活性,纳米钨铜复合材料的制备尤为特殊。本文作者介绍了近年来国内外钨铜复合材料及纳米钨铜复合材料的研究现状,总结分析了其主要制备方法的特点和进行改进需要考虑的问题。The well combination between Cu with preeminent conductivity and W with high-temperature strength and arc-resistance will yield a serial of preeminent properties.Because W and Cu do not dissolve each other,the preparation methods for W-Cu composite material are proved to be particular.And as nanoparticles manifest some unusual properties and intensive activity,the preparation methods for nano W-Cu composite material is more particular.The recent research of W-Cu composite material and nano W-Cu composite material home and abroad is introduced in the paper.The authors analyze and sum up the characteristics of the major preparation methods and suggest the issues involved in the improvement.
