Preparation method of two-dimensional ceramic material toughened aluminum oxide ceramic
The invention discloses a preparation method of two-dimensional ceramic material toughened aluminum oxide ceramic, which comprises the following steps: step 1, uniformly mixing a two-dimensional ceramic material and aluminum oxide under the mechanical stirring of 500-1000 rpm to obtain a dispersion liquid, step 2, spraying the uniformly mixed dispersion liquid from a spray gun at a flow rate of 0.1-10 mL/s, and drying to obtain the two-dimensional ceramic material toughened aluminum oxide ceramic. The method comprises the following steps: 1, spraying aluminum oxide into a two-dimensional ceramic material, generating a low-temperature environment through refrigeration, and rapidly cooling and freezing the sprayed liquid in the low-temperature environment, 3, putting the frozen material in the step 1 into a freeze drying instrument, and drying for 24-50 hours at the temperature of-45-20 DEG C to obtain two-dimensional ceramic material/aluminum oxide mixed powder, and 4, putting the mixed powder into a graphite mold, and carrying out sintering at the temperature of-45-20 DEG C to obtain the two-dimensional ceramic material/aluminum oxide composite material. The two-dimensional ceramic material/aluminum oxide composite block material is obtained through spark plasma sintering, the sintering temperature ranges from 1100 DEG C to 1600 DEG C, the sintering pressure ranges from 20 MPa to 100 MPa, the sintering heat preservation and pressure maintaining time ranges from 5 min to 20 min, and the mass fraction of Ti < 3 > C < 2 > T < x > MXene in the composite block material ranges from 0.1% to 10%.
本发明公开了一种二维陶瓷材料增韧氧化铝陶瓷的制备方法，包括以下步骤：步骤一：将二维陶瓷材料与氧化铝在500rpm‑1000rpm机械搅拌下使得两者均匀混合，从而得到分散液，步骤二：将混合均匀的分散液以0.1mL/s‑10mL/s的流速从喷枪中喷出，通过制冷产生低温环境，使喷出的液体在低温环境中快速冷却结冰，步骤三：将上述步骤中结冰的材料放入冷冻干燥仪中，在温度为‑45～20℃的条件下干燥24～50h，得到二维陶瓷材料/氧化铝混合粉体，步骤四：将上述混合粉体放入石墨模具中，通过放电等离子烧结得到二维陶瓷材料/氧化铝复合块体材料，其中：烧结温度为1100～1600℃，烧结压力为20～100MPa，烧结保温保压时间为5～20min，Ti3C2Tx MXene在复合块体材料中的质量分数为0.1～10％。
