Metal and ceramic connector and connecting method thereof
The invention discloses a metal and ceramic connector and a connecting method thereof, and belongs to the field of metal and ceramic connection. The metal and ceramic connector is of a sandwich layer structure, ceramic is wrapped in metal, and the connecting method comprises the following steps: firstly, performing high-temperature oxidation on the ceramic, performing alloy vacuum casting on a surface-oxidized ceramic sheet, and finally, performing clamping heat treatment on the poured layered composite material, so that metallurgical bonding is generated between the flaky ceramic and the metal. The ceramic is packaged and bound by utilizing the difference of thermal expansion coefficients between metal and ceramic and the interfacial compressive stress generated by lattice difference, so that the mechanical property of the ceramic is improved, and the ceramic is prevented from splashing during fracture.
本发明公开了一种金属与陶瓷连接体及其连接方法，属于金属与陶瓷连接领域，所述金属与陶瓷连接体为三明治层状结构，陶瓷被包覆在金属内部，所述连接方法首先将陶瓷进行高温氧化，对表面氧化的陶瓷片进行合金真空浇铸，最后对浇筑后的层状复合材料夹持热处理，使得片状陶瓷与金属之间产生冶金结合。本发明利用金属和陶瓷之间热膨胀系数的差异以及晶格差异所产生的界面压应力，对陶瓷进行了封装和束缚，提高其力学性能，防止陶瓷在断裂时发生迸溅。
