As one of the widely used methods of material joining in manufacturing industry, brazing is widely used in the fields of medical treatment, power electronics and automobile, etc. Among many joining methods, the brazing is the most effective and promising way of the joining of ceramic/metal dissimilar materials. In this paper, the investigations on the joining of ceramic/metal dissimilar materials in recent 20 years were reviewed in detail. Firstly, the research status of ceramic/metal brazing joint was summarized. Secondly, the research progress of ceramic/metal dissimilar brazing joint was reviewed in detail from four kinds of ceramic materials, including oxide ceramics, carbide ceramics, nitride ceramics and ceramic matrix composites, as well as five kinds of brazing methods including active metal brazing, air reaction brazing, contact reaction brazing, glass brazing and ultrasonic assisted brazing. And then the applications of the ceramic/metal dissimilar brazing joint in medical treatment,power electronics and automobile were introduced. At last, the limitations in the research and development of ceramic/metal dissimilar brazing technology were pointed out, and then the development tendency of ceramic/metal dissimilar brazing technology was expected. The aim of this paper is to provide the theoretical basis and technical support for the investigations of ceramic/metal dissimilar brazing technology based on the summary of relevant researches.
