本成果研制的新型超硬材料刀具,曾获航天部和贵州省多项科技奖。本成果刀片平均硬度HV=6 000;弯曲强度CBN层为350~580 MPa,基底为1.5 GPa;压缩强度2~3GPa;热导率33.5~58.6 W/(m·K);初始氧化温度1 057~1 121℃。和铁族元素不亲合。由于立方氮化硼硬度高,耐磨性好,特别是热稳定 The results of the development of new superhard materials tool, won the aerospace department and Guizhou Province, a number of science and technology awards. The results show that the average blade hardness HV = 6 000; the bending strength CBN layer is 350 ~ 580 MPa, the substrate is 1.5 GPa; the compressive strength is 2 ~ 3 Pa; the thermal conductivity is 33.5 ~ 58.6 W / (m · K); the initial oxidation temperature is 1 057 ~ 1 121 ° C. And iron family elements are not affinity. Due to the high hardness of cubic boron nitride, wear resistance, especially thermal stability
