摘　　要：颗粒增强铝基复合材料具有优良的性能,是当今材料科学与工程领域的研究热点之一。瞬间液相扩散连接(TLP)作为目前连接铝基复合材料的有效连接方法之一备受关注,文中对国内外颗粒增强铝基复合材料TLP技术的研究现状进行了论述。针对目前颗粒增强铝基复合材料TLP焊接技术存在的问题以及未来的发展进行了讨论及探索。采用TLP方法可实现颗粒增强铝基复合材料的连接,相比于其他方法,TLP技术所需温度和压力相对较低,但如何解决氧化膜阻碍、颗粒偏聚、润湿性差等问题仍是未来需攻克的主要难题。复合超声等外场辅助是解决TLP现存问题的可行方向之一。Particle-reinforced aluminum-based composites are one of the research hotspots in the field of materials science and engineering because of their excellent properties.Transient liquid phase(TLP)bonding has attracted much attention as one of the effective bonding methods for joining aluminum-based composites.The research status of particle-reinforced aluminum-based composite TLP bonding technology abroad is discussed.This paper discusses and explores the current problems and future development of TLP welding technology for particle-reinforced aluminum-based composites.The results show that the TLP method can be used to achieve the connection of particle-reinforced aluminum-based composites.Compared with other methods,the temperature and pressure required by the TLP technology are relatively low.However,how to solve the problems of oxide film obstruction,particle segregation,and poor wetness are still the main problems to be overcome in the future.External field assistance such as compound ultrasound is one of the feasible directions to solve the existing problems of TLP.
