摘要:
The present invention provides a method of bonding ceramic and metal comprising the steps of bonding metal foils to a bonding surface of a ceramic matrix and a bonding surface of a metal matrix to be bonded and then heating so as to leave metal layers at the surfaces of the metal foils while forming diffusion layers with inclined linear expansion coefficients with materials of the metal foils diffused in them between the ceramic matrix and metal layer and between the metal matrix and metal layer, and making the respective metal layers which remain at the surfaces of the metal foils bond so as to bond the ceramic matrix and the metal matrix.
摘要(中):
本发明提供一种接合陶瓷和金属的方法,包括以下步骤:将金属箔接合到陶瓷基体的接合表面和待结合的金属基体的接合表面上,然后加热,以使金属层在 金属箔同时形成具有倾斜线性膨胀系数的扩散层,其中金属箔的材料在陶瓷基体和金属层之间以及在金属基体和金属层之间扩散,并且使保留在金属箔表面的各个金属层 金属箔键合以便结合陶瓷基体和金属基体。
