摘　　要：钛合金因其优异的性能,如密度低、耐高温、优异的蠕变和耐腐蚀性等,在航空航天、能源、汽车、建筑、包装与交通运输等诸多领域中得到了广泛应用。然而传统钛合金的高温性能较低,将钛合金与陶瓷连接起来制备成复合结构有助于获得质量较轻、高温性能优良的构件。钎焊在医疗、电力电子和汽车等领域应用广泛,被各国学术界认为是陶瓷/金属异质连接中最有效、最具有发展潜力的连接方式。综述了钛合金与Al_(2)O_(3)、ZrO_(2)等常见陶瓷及ZrB2-SiC及ZrC-SiC等陶瓷基复合材料的钎焊技术研究现状,并介绍了如中间层法等常用的缓解钛合金与陶瓷接头中残余应力的方法,阐述了中间层与复合钎料中增强相的选取,最后指出钛合金/陶瓷异质钎焊技术研究和发展过程中存在的不足,并展望了钛合金/陶瓷异质钎焊技术未来的发展方向,为钛合金/陶瓷异质材料连接的相关研究和工程应用提供理论依据和技术支撑。Titanium alloys have been widely used in many fields such as aerospace,energy,automotive,construction,packaging,transportation,and other fields due to their excellent properties,such as low density,high temperature resistance,excellent creep and corrosion resistance.However,the high-temperature performance of traditional titanium alloys is relatively low.Connecting titanium alloys with ceramics to prepare composite structures can help to obtain components with light weight and excellent high-temperature performance.However,large differences in physical and chemical properties of dissimilar materials often lead to difficulties in joining.Brazing is one of the most widely used methods for connecting materials in the manufacturing industry,and is widely used in medical,power electronics,and automotive fields.Academics around the world believe that brazing is the most effective and promising connection method for ceramic/metal heterogeneous connections.This article summarizes the current research status of brazing titanium alloys to common ceramics such as Al_(2)O_(3)and ZrO_(2),and ceramic matrix composites such as ZrB2-SiC and ZrC-SiC.It also introduces commonly used methods such as interlayer method to alleviate residual stress in titanium alloy ceramic joints,and summarizes the selection of reinforcing phases in interlayer and composite solder.Finally,the shortcomings in the research and development of titanium alloy/ceramic heterogeneous brazing technology are pointed out,and the future development direction of titanium alloy/ceramic heterogeneous brazing technology is prospected,providing theoretical basis and technical support for the related research and engineering application of titanium alloy/ceramic heterogeneous material bonding.
