摘　　要：钨及其合金是制造各类电子光学材料、特殊合金、新型功能材料及有机金属化合物不可或缺的材料,它与异种材料钢、铜等连接形成新构件能够满足不同工作条件对材质的不同要求并发挥不同材料的性能优势,因此,实现钨/钢、钨/铜等异质材料高质量、高可靠连接,对于拓展钨及其合金在冶金、国防、电子、核电等领域的应用具有重要意义。但是,钨与钢、铜等的互溶性有限、物理化学性能差异较大,导致焊接性差。本文综述了国内外关于钨/钢及钨/铜连接技术的研究现状,并展望了钨与异种材料连接的技术方向和发展前景。Tungsten and its alloys are indispensable materials for manufacturing various Electron optics materials,special alloys,new functional materials and organometallic compounds.They are connected with dissimilar materials such as steel and copper to form new components that can meet the different requirements for materials under different working conditions and give play to the performance advantages of different materials.Therefore,the realization of high-quality and reliable connection of tungsten/steel,tungsten/copper and other heterogeneous materials will expand the application of tungsten and its alloys in metallurgy,national defense The applications in fields such as electronics and nuclear power are of great significance.However,the limited mutual solubility and significant differences in physical and chemical properties between tungsten and steel,copper,etc.result in poor weldability.This article summarizes the current research status of tungsten/steel and tungsten/copper bonding technology both domestically and internationally,and looks forward to the technical direction and development prospects of tungsten bonding with dissimilar materials.
