摘　　要：钨铜合金是以钨和铜为主要成分、通过粉末冶金方法制备的一种“假合金”,因兼具良好的导电、导热、高熔点、高电击穿强度、低接触电阻、高耐焊性以及高抗热等性能被广泛应用于电触头、电火花加工电极、电子封装、航空航天等领域。文章根据钨铜合金的性能特点,对其在上述四个领域的应用现状进行了综述;分析了钨铜合金传统制备技术如熔渗、高温液相、活化液相等方法,以及新型制备技术如放电等离子烧结、注射成型、快速定向凝固等方法的特征;阐述了添加剂对合金组织、性能的影响规律。根据文献分析结合课题组的前期研究工作对钨铜合金的制备和应用技术进行了总结和展望。W-Cu Alloy is a pseudo-alloy of copper and tungsten, which is prepared by powder metallurgy. It is widely used in the fields of electric contacts, EDM electrodes, electronic packaging, aerospace and so on due to its high electrical conductivity, thermal conductivity, melting point, electrical breakdown strength, welding resistance, heat resistance and low contact resistance. The application status in the above four fields are summarized in this paper according to the performance of W-Cu alloy. While analyzing traditional technologies such as infiltration method, liquid phase sintering under high temperatures method, activated liquid phase sintering method, the paper also investigated the characteristics of new preparation technologies such as spark plasmon sintering technology, injection molding technology and rapid directional solidification technology. Additionally, the effects of additives on the microstructure and properties of W-Cu alloys are expounded in this paper. Combined the above analysis with the previous research, the preparations and applications of W-Cu alloys are summarized and prospected.
