Al2O3—ZrO2—Y2O3—TiN nanocomposite ceramic powder and preparation method thereof
The present invention provides an Al2O3—ZrO2—Y2O3—TiN nanocomposite ceramic powder and a preparation method thereof, and belongs to the field of ceramic materials. In the ceramic powder provided by the present invention, a molar ratio of Zr:Al:Y:Ti is (30-70):(10-30):(0.4-1):(5-20). The nanocomposite ceramic powder provided by the present invention is good in dispersibility, and does not generate agglomeration, and the mechanical properties of a ceramic material obtained after sintering of the nanocomposite ceramic powder provided by the present invention are better. Proved by results of embodiments, the hardness of a ceramic material obtained by sintering of the nanocomposite ceramic powder provided by the present invention is 28-35 GPa, and abrasion ratio is 4500-6000:1.
