陶瓷与金属连接的研究进展

陶瓷与金属之间存在着性能互补关系，将它们连接在一起，可以拓展各自的应用范围。介绍了各种连接方法的特点和连接机理，着重讨论了钎焊、固相扩散连接、部分瞬间液相连接和自蔓延高温合成连接的机理。指出活性金属钎焊和固相扩散焊技术较成熟，连接强度高，重复性好，广泛应用于连接在中、低温领域服役的陶瓷／金属复合构件，瞬间液相连接是极有发展前途的连接方法。

The Research and Prospect of Ceramic and Metal Bonding

The properties of ceramic and metal have mutual compensation relationship. Their application can be more extensioe by bonding them together. The features and mechanism of various bonding methods are introduced. The mechanisms of brazing, solid phase diffusion bonding, partial transient liquid phase bonding and self-propagating high-temperature synthesis are discussed on emphasis. It shows that reactive brazing and solid phase diffusion bonding method are more mature, with high strength and good repetition joint, and widely used to bond ceramic/metal compound structure for middle and low temperature application. The partial transient liquid phase bonding is the most promising method.
