Boron nitride superhard material containing high-entropy ceramic phase as well as preparation method and application of boron nitride superhard material
The invention belongs to the technical field of superhard composite materials, and particularly relates to a boron nitride superhard material containing a high-entropy ceramic phase and a preparation method and application of the boron nitride superhard material. The boron nitride superhard material containing the high-entropy ceramic phase provided by the invention has high hardness, high strength and high toughness. A small amount of high-entropy ceramic phase powder is introduced into the boron nitride superhard material, and the wettability between a binding phase and boron nitride can be effectively improved and the dissolution and precipitation process can be adjusted by utilizing the multi-principal-element high-entropy effect of the high-entropy ceramic phase, so that the microscopic structure of the boron nitride superhard material is optimized, and the service life of the boron nitride superhard material is prolonged. And finally, the strength, the hardness and the toughness of the boron nitride superhard material are simultaneously improved. According to the boron nitride superhard material containing the high-entropy ceramic phase, the comprehensive mechanical property of the boron nitride superhard material containing the high-entropy ceramic phase can be remarkably improved only by adding 1-10 wt% of the high-entropy ceramic phase powder, the production cost is reduced, and the service life of the boron nitride superhard material containing the high-entropy ceramic phase is prolonged.
本发明属于超硬复合材料技术领域，具体涉及一种含高熵陶瓷相的氮化硼超硬材料及其制备方法和应用。本发明提供的含高熵陶瓷相的氮化硼超硬材料兼具高硬度、高强度和高韧性。本发明在氮化硼超硬材料中引入少量高熵陶瓷相粉末，利用高熵陶瓷相的多主元高熵效应，可以有效改善粘结相与氮化硼之间的润湿性，调节溶解析出过程，从而优化氮化硼超硬材料的显微组织，最终实现氮化硼超硬材料的强度、硬度和韧性的同时提升。本发明只需添加1wt％～10wt％的高熵陶瓷相粉末，即可显著提高含高熵陶瓷相的氮化硼超硬材料的综合力学性能，降低生产成本，延长含高熵陶瓷相的氮化硼超硬材料的使用寿命。
