Medium-entropy nitride ceramic material and preparation method thereof
The invention relates to a medium-entropy nitride ceramic material and a preparation method thereof.The preparation method comprises the steps that TiN powder, TaN powder and NbN powder serve as raw materials, absolute ethyl alcohol is added after the raw materials are mixed, and the mixture is ground in the inert atmosphere to obtain mixed powder; carrying out spark plasma sintering on the mixed powder after compression molding, and naturally cooling to room temperature to obtain the medium-entropy nitride ceramic Ti1-x (Ta1/2Nb1/2) xN (0lt; xlt; 1). According to the invention, the bulk nitride ceramic is successfully synthesized by adjusting the content of Ti and the preparation process. The method not only expands a nitride system, but also has potential application prospects in extremely severe working conditions such as high temperature and high load.
本发明涉及一种中熵氮化物陶瓷材料及其制备方法，是以TiN粉、TaN粉和NbN粉为原料，混合后加入无水乙醇，在惰性气氛中研磨得到混合粉末；再将混合粉末压制成型后进行放电等离子烧结，自然冷却至室温，得到中熵氮化物陶瓷Ti1‑x(Ta1/2Nb1/2)xN(0
