摘要:
陶瓷增强钛基复合材料(CTMCs)兼有高的比强度、比刚度及良好的耐磨性和抗高温氧化性,对其进行有效焊接,有助于加强其在航空航天、机械电子和医疗器械等领域的广泛应用。综述了CTMCs熔化焊、钎焊和固相扩散焊,以及这3种焊接的国内外研究进展,着重回顾了熔化焊焊缝增强体的分布特征、钎料/母材界面行为及扩散焊焊缝孔隙度与接头力学性能之间的关系。并结合具体的焊接工艺,归纳了熔化焊电极移动速度、钎焊和固相扩散焊焊接温度以及保温时间对接头界面行为和力学性能的影响规律。最后,认为需要加强CTMCs的异材连接、界面反应层形成的热力学和动力学,以及界面微结构与接头服役性能(如强度和耐高温性)的关联性研究。
Abstract:
Ceramic reinforced titanium matrix composites (CTMCs) possess high specific strength and stiffness, good wear and high temperature oxidation resistances. The effective joining of CTMCs can contribute to their applications in the fields of aerospace, machinery, electronics, medical apparatus, and instruments, etc. In this paper, the research progresses on fusion welding, brazing and solid phase diffusion bonding of CTMCs are reviewed. The distribution characteristics of reinforcement in the fusion welding seam, the interfacial behavior of brazing filler/base material interface, the relationship between the void ratio at the diffusion-bonding interface and joints mechanical properties are emphatically concerned. Moreover, the influences of processing parameters (such as fusion welding electrode moving speed, joining temperature and holding time of brazing and diffusion bonding) on the interfacial behavior and joint mechanical properties are summarized by combining with the respective joining processes. Finally, we consider that the related investigations on joining of CTMCs, thermodynamics, and dynamics of formation of interfacial reaction layer, the relationship between interfacial microstructures and joint performances (strength and high temperature resistance) need to be strengthened.
