METHODS OF FABRICATING POLYCRYSTALLINE DIAMOND COMPACTS AND RELATED CANISTER ASSEMBLIES

摘要

Embodiments disclosed herein involve polycrystalline diamond (“PCD”) tables and polycrystalline diamond compacts (“PDCs”) that include PCD tables as well as methods and apparatuses for manufacturing thereof. Some embodiments include a canister assembly that may be used in a high-pressure/high-temperature (“HPHT”) process or other heating process to manufacture the PCD tables and/or the PDCs.

主权项

1. A method of manufacturing a polycrystalline diamond compact, the method comprising:
forming a canister assembly including:
a first canister portion and a second canister portion, the first canister portion and the second canister portion collectively defining an internal volume of the canister assembly; anda compact assembly positioned in the internal volume of the canister assembly, the compact assembly including:a polycrystalline diamond element; andphosphorous positioned adjacent to the polycrystalline diamond element; sealing the internal volume of the canister assembly to form a sealed internal volume including the compact assembly; and after sealing the internal volume of the canister assembly, subjecting the canister assembly to one or more of a high-pressure/high-temperature process or a heating process effective to alloy the polycrystalline diamond element with the phosphorous.
