Diamond-enhanced carbide cutting elements, drill bits using the same, and methods of manufacturing the same

摘要

Embodiments for diamond-enhanced carbide cutting elements and drilling apparatuses that include a diamond-enhanced carbide material are disclosed. Embodiments of methods for manufacturing such articles are also disclosed. The diamond-enhanced carbide cutting elements disclosed are at least partially enclosed by a refractory metal structure from a refractory metal can assembly used in the fabrication of the diamond-enhanced carbide cutting element. The diamond-enhanced carbide cutting elements disclosed herein have greater abrasion resistance than tungsten carbide, and a greater toughness than polycrystalline diamond cutters.
