METHOD FOR MANUFACTURING POLYCRYSTALLINE DIAMOND COMPACT ENHANCED BY CVD DIAMOND

摘要

Disclosed are a polycrystalline diamond compact enhanced by CVD diamond and a method for manufacturing same. A CVD diamond strip is embedded into polycrystalline diamond and hard alloy powder and used as an enhancement phase, and after a blank is formed by pressing, a novel polycrystalline diamond compact enhanced by the CVD diamond is obtained by sintering the blank through a high-temperature and high-pressure sintering process and a proper thermal treatment process.
