Ternary boride-zirconium boride composite material and preparation method thereof
The invention relates to a ternary boride-zirconium boride composite material, which is prepared from the following components in percentage by mass: 45.43-80.14% of AlMgB14 powder and 19.86-54.57% ofZrB2 powder. Meanwhile, the invention also discloses a preparation method of the composite material. The AlMgB14-ZrB2 composite material prepared by the preparation method disclosed by the inventionhas very high relative density, relatively high room-temperature/high-temperature hardness and fracture toughness and excellent high-temperature wear resistance, and can be used as a mechanical wear-resistant part used in a high-temperature environment.
本发明涉及一种三元硼化物‑硼化锆复合材料，该复合材料按质量分数计，由45.43~80.14%的AlMgB粉体和19.86~54.57%的ZrB粉体制成。同时，本发明还公开了该复合材料的制备方法。本发明所制备的AlMgB‑ZrB复合材料具有非常高的相对密度，并具有较高的室温/高温硬度和断裂韧性、优异的高温抗磨损性能，可用作高温环境下使用的机械耐磨零部件。
