ABSTRACT:
A method for forming an ultra hard material layer is provided. The method includes disposing a metallic liner inside the periphery of a refractory metal enclosure, introducing ultra hard material feed stock into the enclosure, and sintering using HPHT processing and cooling to form the ultra hard material layer, substantially free of peripheral cracking, chipping and fracturing.
