ABSTRACT:
The present invention is directed to polycrystalline diamond and cubic boron nitride (CBN) composite compacts and a method of making the same under high temperature/high pressure (HP/HT) processing conditions, and more particularly to HP/HT polycrystalline composite compacts having reduced abrasive layer stresses. The method of the invention involves making a metal carbide supported polycrystalline composite compact under conditions of high pressure and high temperature (HP/HT) in an HP/HT apparatus by the following steps:
