METHOD FOR MANUFACTURING CUBIC BORON NITRIDE SINTERED BODY, AND CUBIC BORON NITRIDE SINTERED BODY |
| 摘要 |
Provided is a cubic boron nitride sintered body having good wear resistance and fracture resistance. A method for manufacturing a cubic boron nitride sintered body of the present invention is a method for manufacturing a cubic boron nitride sintered body having a cubic boron nitride particle content of 80% by volume or more and 99% by volume or less. The method includes a first step of preparing cubic boron nitride particles; a second step of coating surfaces of the cubic boron nitride particles with a coating material so as to obtain coated particles; a third step of mixing the coated particles and a binder to obtain a mixture; and a fourth step of sintering the mixture. |
