Abstract
Methods of forming a cutting element include sintering diamond particles at a temperature of at least about 1400° C. under a pressure of at least about 10 GPa in the absence of a metal solvent catalyst so as to form a polycrystalline diamond compact (PDC), providing a barrier material over at least a portion of the PDC, providing a carbide material and a metal binder comprising at least one transition metal element over the barrier material and the PDC, and performing a second sintering process comprising sintering the carbide material, the metal binder, the barrier material, and the PDC at a temperature of at least about 1400° C. under a pressure of at least about 5 GPa to form the cutting element. At least a portion of the PDC proximate an exposed exterior surface of the PDC may be at least substantially free of the metal binder.
