Method for directly preparing composite metal ceramic substrate
The invention belongs to the field of functional ceramics, and discloses a method for directly preparing a composite metal ceramic substrate. The composite metal ceramic substrate comprises a ceramic matrix and a copper foil, the surface of the ceramic matrix is modified through laser, and the copper foil and the ceramic matrix subjected to surface laser modification are combined through hot isostatic pressing sintering. A means of ceramic surface laser modification is utilized; and the ceramic substrate can be prepared by directly combining with metal without the help of other materials. And active metal solder does not need to be added, so that the cost is reduced, and a new substance is formed under limited specific conditions. Therefore, close combination of the ceramic and the metal copper is achieved, and heat stability is good and far higher than that in the prior art under the same process.
本发明属于功能陶瓷领域，公开了一种直接制备复合金属陶瓷基板的方法。复合金属陶瓷基板包括陶瓷基体和铜箔，陶瓷基体通过激光实现表面改性，并使用热等静压烧结将铜箔与表面激光改性后的陶瓷基体结合。利用陶瓷表面激光改性的手段；不需要借助其他材料就可以与金属直接结合制备出陶瓷基板。不需要添加活性金属焊料，减少成本，且通过限定的具体条件下形成了新的物质。从而实现陶瓷与金属铜的紧密结合，具有良好的热稳定性，在同等工艺下远高于现有技术。
