ZrO2 and TiC synergistically toughened Al2O3-based ceramic material and preparation method thereof
The invention provides a ZrO2 and TiC synergistically toughened Al2O3-based ceramic material and a preparation method thereof, and belongs to the field of ceramic materials, aiming at solving the problem that the mode of reinforcing Al2O3-based ceramic by combining three means of phase change toughening, fiber toughening and particle toughening in the prior art is not researched yet. The ceramic material comprises the following components in percentage by volume: 5 to 20 percent of ZrO2 whiskers, 5 to 10 percent of TiC nanoparticles, 0.5 to 3 percent of MnO2, 0 to 1 percent of Y2O3 and the balance of Al2O3. According to the ceramic material, ZrO2 whiskers and TiC nano-particles are added into an Al2O3 matrix, and the Al2O3-based ceramic material which is high in hardness, strength and abrasion resistance and has the advantage of toughness is provided through a reasonable material formula and a reasonable process.
本发明的目的针对于现有技术中相变增韧、纤维增韧和颗粒增韧三种手段相结合增强AlO基陶瓷的方式尚没有研究的问题，提供了一种ZrO和TiC协同增韧的AlO基陶瓷材料及制备方法，属于陶瓷材料领域。陶瓷材料的各组分体积百分比为：ZrO晶须5～20％，TiC纳米颗粒5～10％，MnO0.5～3％，YO0～1％，余量为AlO。该陶瓷材料是在AlO基体中加入ZrO晶须和TiC纳米颗粒，并通过合理的材料配方和工艺，提供一种高硬度、高强度、高耐磨并具有韧性优势的AlO基陶瓷材料。
