    摘要: The disclosure provides a super-abrasive body including a thermally stable polycrystalline diamond (TSP) body having a top region and an enhanced attachment region, wherein the enhanced attachment region includes tungsten carbide particles having a volume of at least 30% of the total volume of the enhanced attachment region. The disclosure further provides a super-abrasive element having the super-abrasive body attached to a substrate via an attachment material located in or around the tungsten carbide particles. The disclosure additionally provides earth-boring drill bits with such a super-abrasive element. Further, the disclosure provides methods of forming such super-abrasive bodies and elements by forming a PCD body with particle of tungsten carbide in an enhanced attachment region, then leaching the PCD body and attaching it to a substrate via an attachment material in or around the tungsten carbide particles.

    摘要: A functionally graded cemented tungsten carbide material produced via heat treating a sintered cemented tungsten carbide is disclosed and described. The heat treating process comprises at least a step that heats the sintered material to the multi-phase temperature range in which multiple phases including solid tungsten carbide, liquid metal binder, and solid metal binder coexist. Additionally, the material, after the heat treating process comprises a surface layer with lower metal binder content than the nominal value of metal binder content of the bulk of the material. The material is used to make tools for rock drilling, machining of metal alloys, and machining of non-metallic materials. The material can also be used to make engineered wear parts that are used in mechanical systems and applications where wear resistance is required or desired.
