Zirconia/alumina ceramic composite material and preparation method thereof
The invention relates to a zirconia/alumina ceramic composite material and a preparation method thereof, which belong to the technical field of alumina ceramics. The preparation method of the zirconia/alumina ceramic composite material comprises the following steps of carrying out vacuum hot pressed sintering on mixed powder of 3Y-ZrO2 and Al2O3, and cooling to obtain the zirconia/alumina ceramic composite material. The mass ratio of the 3Y-ZrO2 to the Al2O3 in the mixed powder is (15-65): 100. According to the preparation method of the zirconia/alumina ceramic composite material, due to the adoption of a hot pressing sintering technology, discharge of closed pores in the sintering preparation process of the material is promoted by pressure, high compactness can be achieved within a short time or at a low temperature, and the interface performance of the material is optimized; furthermore, the frictional wear performance and the like of the zirconia/alumina ceramic composite material are obviously improved.
本发明涉及一种氧化锆/氧化铝陶瓷复合材料及其制备方法，属于氧化铝陶瓷技术领域。本发明的氧化锆/氧化铝陶瓷复合材料的制备方法，包括以下步骤：将3Y‑ZrO2和Al2O3的混合粉体进行真空热压烧结，冷却，即得；所述混合粉体中3Y‑ZrO2和Al2O3的质量比为15～65:100。本发明的氧化锆/氧化铝陶瓷复合材料的制备方法，由于采用了热压烧结技术，压力促进材料烧结制备过程中闭气孔的排出，在较短时间或较低温度下能够实现较高致密度，优化材料界面性能，进而显著提高氧化锆/氧化铝陶瓷复合材料的摩擦磨损等性能。
