High-entropy ceramic material with excellent tribological properties and preparation method thereof
The invention relates to a high-entropy ceramic material with excellent tribological properties. The material is block-shaped, the composition of the material is (Hf-Mo-Nb-Ta-Ti-) C, the ceramic material is prepared from the following raw materials in percentage by mass: 1.2 to 21.9 percent of HfO2, 14.5 to 15.0 percent of MoO3, 13.4 to 13.8 percent of Nb2O5, 2.3 to 23.0 percent of Ta2O5, 8.0 to 8.3 percent of TiO2 and 18.0 to 20.6 percent of graphite powder. Meanwhile, the invention further discloses a preparation method of the high-entropy ceramic material. The ceramic material provided by the invention has good tribological properties and mechanical properties in a wide temperature range, and can realize lubrication at a specific temperature, thus realizing structural/lubricating function integrated design of the ceramic material.
本发明涉及一种具有优异摩擦学性能的高熵陶瓷材料，该材料呈块体，其组成为(Hf‑Mo‑Nb‑Ta‑Ti‑)C，由下述质量百分比的原料制得：HfO221.2~21.9%，MoO314.5~15.0%，Nb2O513.4~13.8%，Ta2O522.3~23.0%，TiO28.0~8.3%和石墨粉末18.0~20.6%。同时，本发明还公开了该高熵陶瓷材料的制备方法。本发明在宽温域具有良好的摩擦学性能和力学性能，并且可实现特定温度的润滑，从而实现了陶瓷材料的结构/润滑功能一体化设计。
