COATED CUBIC BORON NITRIDE PARTICLE AND METHOD OF MANUFACTURING SAME
A cubic boron nitride particle according to an aspect of the present invention includes multiple coating layers formed on a surface thereof, so that the surface of the cBN particle is not directly exposed compared to the case of using a single coating layer. Accordingly, when a PCBN sintered body is formed, since the cBN particles are not directly bonded to each other, the jagged portion of the surface thereof may be reduced to thus improve fluidity when the cBN particles are mixed with the binder. A method of manufacturing a cubic boron nitride particle according to another aspect of the present invention includes a coating-layer treatment step performed so that the surface of the coating layer particle is smoothed and the particle shape is adjusted so as to be close to the circular shape after a first-coating-layer forming step.
