Preparation method of ceramic/metal composite material
The invention belongs to the field of welding, and discloses a preparation method of a ceramic/metal composite material. Metallization is rapidly achieved on the surface of the ceramic through laser scanning marking, and the ceramic/metal composite material is prepared from the metalized ceramic and copper through hot isostatic pressing sintering. The problems that ceramic and metal are poor in wettability and not easy to combine, and the preparation cost is high are solved, and the cost is reduced by conducting pretreatment on a laser metal foil on the ceramic surface; the treatment time is short, the process temperature is low, and the operation is safer. According to the preferable embodiment of the invention, the transition layer of about 6 microns exists, the binding force of the composite material can be well increased due to the existence of the transition layer, and the peel strength can reach 9.94 N/mm.
本发明属于焊接领域，公开了一种陶瓷/金属复合材料的制备方法。通过激光扫描标刻在陶瓷表面快速实现金属化，将金属化后的陶瓷与铜通过热等静压烧结制备出陶瓷/金属复合材料。以解决陶瓷与金属润湿性差不易结合、制备成本高的问题，通过在陶瓷表面激光金属箔片进行前处理，降低成本；且处理时间短，工艺温度低，操作更安全。本发明优选的实施例，存在约6μm的过渡层，过渡层的存在可以很好地增大复合材料的结合力，剥离强度可以达到9.94N/mm。
