Polycrystalline diamond compact with improved thermal stability
The present invention relates to a polycrystalline diamond compact. A method for manufacturing a polycrystalline diamond compact includes: preparing primary sintering by mixing and assembling first diamond particles and metal binder particles; sintering the mixed and assembled particles; leaching the upper surface of the sintered polycrystalline diamond compact; preparing secondary sintering by mixing second diamond particles and the metal binder particles and assembling the mixed particles on the upper surface of the primarily sintered polycrystalline diamond compact; sintering the sintered polycrystalline diamond compact and the mixed particles of the upper part; and a grinding step of grinding the reassembled second diamond particles and metal binder particles so as to remove the same. The polycrystalline diamond compact minimizes the content of the residual metal binder in a surface layer and increases the content of the diamond particles with high thermal conductivity, thereby increasing the lifespan of the polycrystalline diamond compact.
