钽是一种具有极好的耐蚀性、良好的加工性及可焊性等优异性能的难熔金属,但精炼工艺复杂,生产成本高,与异种金属的复合不但可以节约生产成本,还能使材料结构轻量化。不锈钢是一种广泛应用的结构材料,其化学性质和综合性能均较好。基于钽和不锈钢某些关键性能上的共性,将其复合极为重要。但由于二者焊接接头的强度和耐蚀性往往不理想,焊接出安全优质的复合构件成了全球共有的难题。针对这一问题,本文综述了近些年国内外研究人员关于引入中间层材料作为过渡介质来改善钽与不锈钢之间接头性能的研究,得出了不同焊接工艺对钽与不锈钢焊接接头性能及适用场合的影响,提出了相关技术和焊接工艺方面的改进方法,对钽与不锈钢焊接中添加中间层的未来研究方向进行展望,为钽与不锈钢复合构件的广泛应用提供一定的技术支持和理论指导,推动相关领域的发展与进步。
Tantalum is a refractory metal with excellent corrosion resistance
good machinability and weldability
but its refining process is complicated and the production cost is high. The composite with dissimilar metals can not only save production costs
but also make the material structure lightweight. Stainless steel is a widely used structural material
its chemical properties and comprehensive properties are good. Due to the commonality of tantalum and stainless steel in some key properties
it is extremely important to combine them. However
due to the strength and corrosion resistance of the welded joints of the two are often not ideal
welding safe and high-quality composite components has become a common problem in the world. In view of this problem
this paper reviews the study of researchers at home and abroad in recent years on the introduction of intermediate layer materials as transition media to improve the joint properties between tantalum and stainless steel
and obtains the influence of different welding processes on the properties and application occasions of tantalum and stainless steel welded joint
and puts forward the improvement methods of related technologies and welding processes. The future research direction of adding intermediate layer in the welding of tantalum and stainless steel is prospected
which provides certain technical support and theoretical guidance for the wide application of tantalum and stainless steel composite components
and promotes the development and progress of related fields.
