Abstract:
1. A high energy treated cutter, comprising: a substrate having a top surface, an outer region, an inner core being at least partially surrounded by the outer region, and an interface disposed between the inner core and the outer region, wherein the substrate comprises a mixture of a metallic material and a binder material, at least a portion of the outer region having a lower concentration of the binder material than the inner core, the interface having a highest concentration of binder material than the inner core and the outer region; and a wear resistant layer coupled to the top surface of the substrate, wherein the substrate has been exposed to a high energy treatment, and wherein the wear resistant layer has been protected from exposure to the high energy treatment using a protective cover, and wherein the interface extends to the outer perimeter of the substrate at a distance away from the top surface.
