是采用與其它PCD產(chǎn)品相同的超高壓－高溫技術(shù)制造的聚晶產(chǎn)品，由于它所用結(jié)合劑在高溫時不與金剛石反應(yīng)且其熱脹系數(shù)與金剛石接近，其耐高溫高達攝系1200度，SFTSP主要用于制造地質(zhì)鉆頭及石油鉆頭等
Polycrystalline diamond (PCD) is diamond powder polycrystalline products produced by sintering together selected synthetic diamond with a metal matrix using very sophisticated high-temperature and high-pressure technology. Polycrystalline diamond (PCD) widely used in natural diamond bruting,geological drill bits,oil well drill bits and other PCD dressing tools
