Carburized tungsten tetraboride superhard material and preparation method thereof
The invention relates to a carburized tungsten tetraboride superhard material. The material is a WB4-TB block material composed of a WB4 phase and a T-B phase. The Vickers hardness of the material under the load of 0.49 N is 63.05 GPa, the electric conductivity is 1.7 * 10 < 5 > S/m, and the fracture toughness measured by a unilateral precrack beam method is 4.7 +/-0.5 MPam1/2. Meanwhile, the invention also discloses a preparation method of the material. The WB4-TB material obtained by the invention has ultrahigh hardness and conductivity, meanwhile, the preparation equipment is simple, the preparation process is mild, and the WB4-TB material is economical and practical, and has important application prospects in the fields of wear-resistant materials and machining.
本发明涉及一种渗碳的四硼化钨超硬材料，该材料是由WB4相和T‑B两相组成的WB4‑TB块体材料；且该材料在0.49 N载荷下的维氏硬度为63.05 GPa，导电率为1.7×105S/m，单边预裂纹梁法测得断裂韧性为4.7±0.5 MPa•m1/2。同时，本发明还公开了该材料的制备方法。本发明获得的WB4‑TΒ材料具有超高硬度与导电，同时制备设备简单，制备工艺温和，经济实用，在耐磨材料和机械加工领域具有重要的应用前景。
