Document Type and Number:
WIPO Patent Application WO/2014/156625
Kind Code:
A1
Abstract:
Provided is a cubic boron nitride sintered body having excellent wear resistance and defect resistance. This method for manufacturing a cubic boron nitride sintered body is a method for manufacturing a cubic boron nitride sintered body containing 80-99% by volume of cubic boron nitride particles, and is characterized in including a first step for preparing the cubic boron nitride particles, a second step for obtaining coated particles by coating the cubic boron nitride particles with a coating material, a third step for obtaining a mixture by mixing the coated particles and a bonding material, and a fourth step for sintering the mixture.
