Ceramic composite material as well as preparation method and application thereof
The invention provides a ceramic composite material as well as a preparation method and application thereof, and belongs to the field of composite materials. The ceramic/metal mixed layer is arranged between the ceramic matrix and the nanocrystalline layer, the bonding strength of the ceramic matrix and the nanocrystalline layer can be enhanced, meanwhile, the ceramic/metal mixed layer can form pressure stress on the subsurface of the ceramic matrix, and the fatigue strength of the ceramic composite material is improved; the metal carbide in the nanocrystalline layer is high in melting point and good in stability at high temperature, and the amorphous carbon film with excellent wear resistance is adopted to wrap the nanocrystalline, so that the high-temperature stability and wear resistance can be enhanced, and the bonding strength between the nanocrystalline layer and the structural layer of the amorphous carbon film wrapped nanocrystalline can be improved; the fatigue strength of the ceramic composite material, the bonding strength between layers, the wear resistance and the high-temperature stability are improved, so that the service life of the ceramic composite material serving as a ceramic strip of a printer is prolonged.
本发明提供了一种陶瓷复合材料及其制备方法和应用，属于复合材料领域。本发明在陶瓷基体和纳米晶层的中间设置陶瓷/金属混合层，可以增强陶瓷基体与纳米晶层的结合强度，同时陶瓷/金属混合层能在陶瓷基体亚表面形成压应力，提高陶瓷复合材料的疲劳强度；纳米晶层中的金属碳化物熔点高，在高温下稳定性好，并且本发明采用耐磨性能优异的非晶碳膜包裹纳米晶，既可以增强高温稳定性和耐磨性能，又可以提高纳米晶层与非晶碳膜包裹纳米晶的结构层之间的结合强度；陶瓷复合材料的疲劳强度、各层之间的结合强度、耐磨性能和高温稳定性的提高延长了其作为打印机的陶瓷条的使用寿命。
