Abstract
Embodiments of the invention relate to methods of making articles having portions of polycrystalline diamond bonded to a surface of a substrate and polycrystalline diamond compacts made using the same. In an embodiment, a molding technique is disclosed for forming cutting tools comprising polycrystalline diamond portions bonded to the outer surface of a substrate.
Claims6
A method of making a polycrystalline diamond (“PCD”) structure, the method comprising:
- providing a substrate having a surface;
- positioning at least one diamond material flute volume including at least one diamond material tube including diamond particles, the at least one diamond material tube in contact with a portion of the surface of the substrate;
- and
- subjecting the substrate and the at least one diamond material flute volume to a high-pressure/high-temperature (“HPHT”) process effective to sinter the diamond particles to form a PCD flute volume and bond the PCD flute volume.
