| titleOfInvention | Spiral dislocation type cubic boron nitride and preparation method thereof, cutter and drill bit |
| abstract | Helical dislocation type cubic boron nitride and a preparation method thereof, a cutter and a drill bit; relates to the field of nitrides. The crystal of the screw dislocation type cubic boron nitride has a screw dislocation structure, and the diameter of a screw dislocation core is 1 to 50 nm. The preparation method of the spiral dislocation type cubic boron nitride comprises the steps of carrying out strain treatment on blocky polycrystalline cubic boron nitride under the pressure of more than 1GPa and the temperature of more than 600 ℃, generating a spiral dislocation structure in crystal lattices of the polycrystalline cubic boron nitride, and annealing to eliminate residual stress. The application provides a spiral dislocation type cubic boron nitride has strong hardness and good thermal stability, can be applied to fields such as cutter, drill bit as superhard materials. |
