POLYCRYSTALLINE DIAMOND COMPACTS AND RELATED DRILL BITS |
摘要 |
In an embodiment, a polycrystalline diamond compact (“PDC”) comprises a cemented carbide substrate including a first cemented carbide portion and a second cemented carbide portion bonded to the first cemented carbide portion and exhibiting an erosion resistance that is greater than the first cemented carbide portion. The PDC further comprises a polycrystalline diamond (“PCD”) table bonded to the first cemented carbide portion. The PCD table includes a plurality of bonded diamond grains exhibiting diamond-to-diamond bonding therebetween, with the plurality of bonded diamond grains defining a plurality of interstitial regions.
