Polycrystalline diamond composite has high abrasion resistance and impact toughness because of the polycrystalline diamond layer,which are wildly used in petroleum, geology,exploitation drilling of coal and machining field.This paper mainly introduces the development,problems and development trend of polycrystalline diamond composite in domestic,in order to provide the necessary reference for the healthy development of the PDC.
