Polycrystalline Diamond Compact(PDC) is sintered with diamond and WC under ultrahigh pressure and temperature. Combining with the advantages of diamond and WC, PDC is with extremely high wear resistance and excellent impact strength. It is widely used in drilling for all sorts of geological terrane. Such as oil,geological and engineering drilling, etc.
TSP is unsupported polycrystalline diamond. It is with extremely high wear resistance and thermal stability(up to 1200) and high density structure. TSP is widely used in making drilling bits for petroleum and geology prospecting, and tools for diamond and machinery processing. Different shapes( cylinder, conical, square, triangle and hetrerotypic etc. ) can be offered.
