Mo and W co-doped non-equal-ratio high-entropy carbide ceramic material and preparation method thereof
The invention relates to a Mo and W co-doped non-equal-ratio high-entropy carbide ceramic material and a preparation method thereof. The material is characterized in that the molecular formula of the material is (Mo1/2W1/2) 1-x (Ti1/3V1/3Nb1/3) xC (x is not equal to 0.6, 0lt, xlt, 1), and Mo and W are key elements for component and performance adjustment; the preparation method comprises the following steps: taking Mo2C powder, TiC powder, V8C7 powder, NbC powder, WC powder and graphite as raw materials, mixing, adding stearic acid, and grinding under the protection of inert atmosphere to obtain mixed powder; and performing compression molding on the mixed powder, performing hot pressed sintering, and naturally cooling to room temperature to obtain a target product. The non-equal-ratio high-entropy carbide ceramic is successfully synthesized by adjusting the contents of Mo and W and the preparation process. The high-entropy carbide system is expanded, and potential application prospects are achieved under extremely severe working conditions such as high temperature and high load.
本发明涉及一种Mo、W共掺非等比高熵碳化物陶瓷材料及其制备方法。该材料特点在于其分子式为(Mo1/2W1/2)1‑x(Ti1/3V1/3Nb1/3)xC（x≠0.6,0
