Preparation method of zirconium oxide-titanium carbide/zirconium oxide co-fired ceramic composite material
The invention relates to a preparation method of a zirconium oxide-titanium carbide/zirconium oxide co-fired ceramic composite material. The preparation method comprises the following steps: (1) preparing Y2O3 stable nano ZrO2 powder and micron TiC powder as raw materials; carrying out ball milling to obtain a ball-milled wet material; (2) drying, grinding and crushing into powder; (3) dropwise adding a polyvinyl alcohol aqueous solution, stirring, mixing and sieving; (4) after standing, putting into a core mold, and carrying out dry pressing to obtain a TiC/ZrO2 round billet; (5) preparing the Y2O3 stabilized nano ZrO2 powder into granulated powder by adopting a spray granulation method; (6) combining the granulation powder and the TiC/ZrO2 round billet by using an external mold; (7) performing dry pressing to obtain a composite round billet; and (8) carrying out pressureless sintering after drying. The ZrO2-TiC/ZrO2 co-fired ceramic composite material disclosed by the invention has good electrical properties and mechanical properties; the method can be well applied to wearable intelligent products; the interface bonding strength is good, and the requirement that different parts of the ceramic material are suitable for different applications is met.
