METHOD OF FORMING POLYSTALLINE DIAMOND ELEMENTS, POLYCRYSTALLINE DIAMOND ELEMENTS, AND EARTH BORING TOOLS CARRYING SUCH POLYCRYSTALLINE DIAMOND ELEMENTS |
摘要 |
<p>Methods of forming polycrystalline diamond elements include forming a polycrystalline diamond element. A Group VIII metal or alloy catalyst is employed to form the polycrystalline diamond compact table at a pressure of at least about 6.5 GPa or greater. The catalyst is then removed from at least a portion of the table to a depth from a working surface thereof, and may be removed from the entirety of the table. Polycrystalline diamond elements include such polycrystalline diamond compact tables. Earth-boring tools include such polycrystalline diamond elements carried thereon and employed as cutting elements.</p> |
