Hybrid particle sintered polycrystalline diamond in thermal stability and wear ratio has advantages

Hybrid particle sintered polycrystalline diamond in thermal stability and wear ratio has advantages to the powder sintering process development, currently has similar DeBeers company's products and enter the application, that is fine-grained diamond  polycrystalline diamond sintered Si as binder, the impact toughness and wear ratio has advantages, but in the study similar to the U.S., GE growth type polycrystalline diamond, the progress is slow. From oil drilling field  abrasive grinding  combines the above  Abrasive grinding wheel , is no longer the main indicators of wear ratio, self-sharpening drills and impact toughness needed to adapt to complex formation, increase drilling speed has a decisive role, these two indicators thus elevated to the primary location.
