Compared with the ordinary diamond diamond with boron has strong antioxidant activity, high heat resistance

Compared with the ordinary diamond diamond with boron has strong antioxidant activity, high heat resistance, chemical inertness, impact toughness and good semiconducting properties and other characteristics. More widely used in the polycrystalline diamond composite sheet, so that the synthesis of boron-containing  synthetic diamond powder  diamond compact with high impact toughness and heat resistance, increase its service life, as well as facilitate the use of electric arc processing equipment. In this thesis, the top six sides in the domestic synthetic  synthetic diamond  on the use of catalytic Co infiltration method successfully synthesized diamond with boron added growth type Φ19mm drilling boron polycrystalline  abrasive grinding . The samples were abrasion resistance, impact resistance, heat resistance and other properties were tested using SEM, EDS, XRD, DSC-TG and other analytical tools, analysis of the microstructure of the samples, the high temperature binder Co high-pressure synthesis during infiltration behavior and distribution, polycrystalline diamond compact complex mechanism. Ultimately determine the appropriate process parameters for stable production
