摘要: 陶瓷材料具有强度高、耐腐蚀性能好等优点,其与金属的连接结构可以满足航空航天、核能与化工等领域对结构的轻量化、高温与耐腐蚀日益提高的要求。但由于陶瓷与金属的热膨胀系数不匹配,焊接降温过程中会在接头内产生残余应力,削弱接头的连接质量。综述复合钎料法、中间层法与陶瓷表面结构设计法三种常用的陶瓷-金属接头残余应力调控方法的研究现状,并介绍超快激光与闪连两种新型局部加热陶瓷-金属焊接新方法的研究进展,讨论适用于陶瓷-金属接头残余应力测量方法及原理,并总结了陶瓷-金属接头残余应力分布测量的研究现状,最终展望了陶瓷-金属接头残余应力调控与测量未来的发展趋势。

Abstract: Ceramics have shown advantages such as high strength and corrosion resistance. The structures achieved by joining ceramics with metals could fulfill the growing requirements of lightweight, high temperature and corrosion resistance by aerospace engineering, nuclear and chemical engineering. However, due to the mismatch between the thermal expansion coefficient between ceramics and metals, high residual stress could be generated in the joint during the cooling process and deteriorate the reliability of the joint. This paper reviews the research progress of the three most commonly used residual stress controlling methods for ceramic-metal joint, including composite brazing alloy method, interlayer method and ceramic surface design method. The development of the newly invited methods such as femtosecond laser welding and flash joining via local heating is also introduced. The methods suitable for measuring the residual stress in ceramic-metal joints and the corresponding theory are discussed. The research progress on the measurement of the residual stress in ceramic-metal joints is summarized. The future development of the control and measurement of the residual stress in ceramic-metal joints is presented.

Key words: ceramic, metal, control of residual stress, measurement of residual stress
