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.
Claims11
A method of making a polycrystalline diamond (“PCD”) structure having a substrate and at least one PCD portion, the method comprising:
- providing a can formed at least partially by three-dimensional (3-D) printing;
- positioning the substrate and diamond particles within the can;
- and
- subjecting the substrate and the diamond particles positioned within the can to a high-pressures/high-temperature (“HPHT”) process effective to sinter the diamond particles and bond the at least one PCD portion at least partially formed from the diamond particles to a portion of the substrate.
