| titleOfInvention | A kind of synthetic method of the composite superhard material with high-fracture toughness |
| abstract | A kind of synthetic method of composite superhard material with high-fracture toughness of the present invention belongs to the technical field of superhard material preparation.The present invention realizes the welding of diamond particles using fullerene and Nano diamond powder as predecessor under high-temperature and high-pressure conditions；The sintering processes that 15GPa, 2100K, heat-insulation pressure keeping 20min are carried out in large cavity press, are made composite superhard material.There is composite superhard material preferable crystallinity, fracture toughness to have obtained apparent enhancing.The method of the present invention is simple, easily operated；Fullerene is evenly distributed in diamond crystals, has the contact area of bigger with diamond particles, therefore have outstanding fracture toughness, and fracture toughness can also be regulated and controled by controlling the content of fullerene in predecessor. |
