摘要 |
<p>Methods of manufacturing sintered superabrasive structures are disclosed. For example, a plurality of agglomerated granules comprising at least one superabrasive material may be provided and exposed to a pressure and a temperature sufficient to sinter the at least one superabrasive material. In another example, a plurality of agglomerated granules comprising diamond may be provided and exposed to a pressure and a temperature sufficient to form polycrystalline diamond. Articles of manufacture including at least one superabrasive material are disclosed. For example, a polycrystalline diamond compact may comprise a volume of polycrystalline diamond bonded to a substrate, wherein the volume of polycrystalline diamond includes a plurality of agglomerated granules which have been sintered. A drill bit comprising at least one cutting element including a volume of polycrystalline diamond bonded to a substrate wherein the volume of polycrystalline diamond includes a plurality of agglomerated granules which have been sintered is disclosed.</p> |
