Boron doped Polycrystalline diamond compacts(BD-PCD)

BD-PCD boron-containing diamond composite sheet was synthesized by polycrystalline diamond (PCD) under the conditions of high temperature and high pressure, using the co-infiltration catalyst. At the same time in order to improve the heat resistance and impact resistance of PCD, in the process of adding heat resistance is higher, impact toughness and grinding better, more chemically inert boron-containing diamond powder, boron-containing diamond composite. Boron doping process will be a mixture of diamond crystals and boron-containing alloy in the high temperature and high pressure environment, through the diffusion of boron into the diamond crystal, the synthesis of boron-containing diamonds.
