Low-temperature sintering method of conductive ceramic composite material as well as product thereof, and application of conductive ceramic composite material
The invention discloses a low-temperature sintering method of a conductive ceramic composite material. The low-temperature sintering method comprises the following steps: (1) proportioning raw materials 3YSZ and TiN according to chemical composition, adding a sintering aid, adding deionized water, carrying out wet ball milling, and performing drying; (2) sintering the ball-milled and dried powder obtained in the step (1) in a vacuum atmosphere under the pressure of 60-90 MPa at a sintering temperature of less than or equal to 1000 DEG C so as to obtain a sintered product; and (3) performing polishing to remove carbon foil on the surface of the sintered product to obtain the conductive ceramic composite material. The invention further discloses the conductive ceramic composite material prepared through the low-temperature sintering method and application of the conductive ceramic composite material to a pantograph slide plate. According to the sintering method, low-temperature dense sintering of the conductive ceramic composite material is realized, sintering time is effectively shortened, and preparation cost is reduced; and the prepared conductive ceramic composite material has excellent conductivity and mechanical properties.
本发明公开了一种导电陶瓷复合材料的低温烧结方法：(1)将原料3YSZ、TiN按化学组成进行配料，再添加烧结助剂，加入去离子水湿法球磨后烘干；(2)将步骤(1)球磨烘干后的粉料在真空气氛和压力为60～90MPa下进行烧结，烧结温度小于等于1000℃，得到烧结产物；(3)打磨去除烧结产物表面的碳箔后，得到导电陶瓷复合材料。本发明还公开了上述低温烧结方法制备得到的导电陶瓷复合材料及其在受电弓滑板上的应用。该烧结方法实现了导电陶瓷复合材料的低温致密烧结，有效减少了烧结时间，降低了制备成本；且制备的导电陶瓷复合材料具有优异的导电性能和力学性能。
