Easy-to-sinter wear-resistant friction-reducing high-entropy ceramic material and preparation method thereof
The invention relates to an easy-to-sinter wear-resistant and friction-reducing high-entropy ceramic material which is in a block shape and has the composition of (Hf-Mo-Nb-Ta-Ti) C-xAl, wherein x is equal to 0.5-9. Meanwhile, the invention also discloses a preparation method of the material. From the perspective of reducing the sintering temperature and the sintering pressure of the carbide high-entropy ceramic and improving the tribological performance of the carbide high-entropy ceramic, the sintering activity of the carbide high-entropy ceramic is improved by adding a second phase (Al); and the prepared carbide high-entropy ceramic material has excellent mechanical properties (hardness) and tribological properties (low wear and friction coefficient) in a wide temperature range, and is especially suitable for special workpieces requiring high hardness and keeping low frictional wear under service conditions.
本发明涉及一种易烧结的抗磨减摩高熵陶瓷材料，该材料呈块体，其组成为(Hf‑Mo‑Nb‑Ta‑Ti)C‑xAl，x=0.5~9。同时，本发明还公开了该材料的制备方法。本发明从降低碳化物高熵陶瓷的烧结温度、烧结压力和改善其摩擦学性能的角度出发，通过添加第二相（Al）来改善碳化物高熵陶瓷的烧结活性，使所制备的碳化物高熵陶瓷材料在宽温域兼具优异的力学性能（硬度）和摩擦学性能（低磨损和摩擦系数），特别适用于在服役工况下要求较高硬度同时保持较低摩擦磨损的特殊工件。
