DUAL SWEEP DESIGN FOR MANUFACTURING POLYCRYSTALLINE DIAMOND COMPACT

摘要

A method for forming a polycrystalline diamond compact (PDC) includes steps of disposing a first catalyst source on a top of a plurality of diamond crystals; disposing a second catalyst source at a bottom of the plurality of diamond crystals; and applying high temperature and high pressure to the plurality of diamond crystals, the first catalyst source and the second catalyst source such that the plurality of diamond crystals are sintered into a polycrystalline diamond compact.
