Abstract

Machining and cutting tools including, but not limited to, rotary drill bits, mining tools, milling tools, wood shredders, reamers and wire dies formed with at least one substrate having a layer of polycrystalline diamond disposed thereon. The polycrystalline diamond layer may be generally described as a polycrystalline diamond compact (PDC) or PDC layer. The PDC may be formed by using an intermetallic aluminide catalyst. One example of such catalyst may include nickel aluminide used to form diamond to diamond bonds between adjacent diamond particles.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Application No. 60 / 883,938, entitled “Intermetallic Aluminide Polycrystalline Diamond Compact (PDC) Cutting Elements,” filed Jan. 8, 2007.TECHNICAL FIELD[0002]The present disclosure is related to rotary drill bits and associated cutting elements and more particularly to fixed cutter drill bits and associated cutting elements and / or inserts with hard layers of cutting material disposed on at least one portion of the cutting elements and / or inserts.BACKGROUND OF THE DISCLOSURE[0003]Polycrystalline Diamond compositions were originally developed by General Electric. An early reference to manufacture of these composites in an ultra high pressure press is U.S. Pat. No. 3,141,746 to De Lai. In this reference De Lai describes a family of metals that may be used to provide a catalyst for diamond to diamond bonding in the manufacture of a polycrystalline diamond composi...
