TiN-Mo2C composite material and preparation method thereof
The invention discloses a Mo2C combined TiNx composite material and a preparation method thereof, the Mo2C combined TiNx composite material comprises the following chemical components in percentage byvolume: 10-40% of Mo2C powder and the balance of TiNx, x is more than or equal to 0.3 and less than or equal to 0.9, or x is equal to 1.1-1.3. The preparation method comprises the following steps: S1, preparing the TiNx with the particle size of 150 nm or less; S2, preparing the Mo2C with the particle size of 150 nm or less; and S3, performing mixing, pre-pressing and spark plasma sintering to obtain the Mo2C combined TiNx composite material. According to the TiN-Mo2C composite material and the preparation method thereof, the sintering temperature can be reduced through vacancies in the TiNx,the hardness and fracture toughness of the TiNx are improved, the problem that transition carbide is difficult to sinter is solved, and the TiN-Mo2C composite material with higher hardness is obtained through SPS sintering.
本发明公开了一种Mo2C结合的TiNx复合材料及其制备方法，材料的化学成分的体积百分比为：10～40％的Mo2C粉，其余为TiNx，0.3≤x≤0.9或x＝1.1～1.3。其制备方法包括如下步骤：S1：制备150nm以细的TiNx；S2：制备150nm以细的Mo2C；S3：混料、预压、放电等离子烧结制得制得Mo2C结合的TiNx复合材料。本发明利用TiNx中的空位能降低烧结温度，提高其硬度及断裂韧性，解决了过渡族碳化物较难烧结的问题，并通过SPS烧结，获得硬度更高的TiN‑Mo2C复合材料。
