Abstract:
A method for making a treated super-hard structure, the method including providing a super-hard structure comprising super-hard material selected from polycrystalline cubic boron nitride (PCBN) material or thermally stable polycrystalline diamond (PCD) material; subjecting the super-hard structure to heat treatment at a treatment temperature of greater than 700 degrees centigrade at a treatment pressure at which the super-hard material is not thermodynamically stable, for a treatment period of at least about 5 minutes to produce the treated super-hard structure.
