Ceramic/metal brazing structure and ceramic metallization method
The invention provides a ceramic/metal brazing structure and a ceramic metallization method. The ceramic/metal brazing structure comprises a ceramic substrate, and also comprises a metallized bottom layer, which is formed by depositing a biocompatible metal I on the surface of the ceramic substrate; and a metallized top layer, which is formed by depositing a biocompatible metal II on the surface of the metallized bottom layer; wherein the deposition diffusion speed of the biocompatible metal I is greater than that of the biocompatible metal II. The metalized bottom layer is formed on the surface of the ceramic substrate through deposition of the biocompatible metal I, the deposition diffusion speed of the biocompatible metal I is large, the binding force is high, and the metalized bottom layer and the ceramic substrate can be reliably combined. The deposition diffusion speed of the biocompatible metal II is small, a precious metal brazing material is effectively paved and wetted on a metal film during the brazing process, and the reliability of subsequent brazing is guaranteed while tight combination of the film layer and the ceramic matrix is guaranteed.
本发明提供一种陶瓷/金属钎焊结构及陶瓷金属化方法，陶瓷/金属钎焊结构包括陶瓷基底，还包括：金属化底层，通过生物相容性金属I沉积在陶瓷基底表面形成；金属化顶层，通过生物相容性金属II沉积在金属化底层表面形成；所述生物相容性金属I的沉积扩散速度大于生物相容性金属II的沉积扩散速度。本发明在陶瓷基底表面通过生物相容性金属I沉积形成金属化底层，生物相容性金属I的沉积扩散速度大，结合力高，能够使金属化底层与陶瓷基底可靠结合；生物相容性金属II的沉积扩散速度小，能够实现钎焊过程中贵金属钎料在金属膜层上的有效铺展润湿，在保证膜层与陶瓷基体紧密结合的同时保障了后续钎焊的可靠性。
