Polycrystalline diamond compacts, methods of making same, and applications therefor |
摘要 |
Embodiments of the invention relate to polycrystalline diamond compact (“PDC”) including a polycrystalline diamond (“PCD”) table that bonded to a cobalt-nickel alloy cemented carbide substrate. The cobalt-nickel alloy cemented carbide substrate provides both erosion resistance and corrosion resistance to the cemented carbide substrate. In an embodiment, a PDC includes a cemented carbide substrate including cobalt-nickel alloy cementing constituent. The PDC further includes a PCD table bonded to the cemented carbide substrate. |
