METHOD OF MAKING CARBONATE PCD AND SINTERING CARBONATE PCD ON CARBIDE SUBSTRATE

摘要

A method of forming a polycrystalline diamond body includes mixing a sintering agent with diamond powder to form a premixed layer, wherein the sintering agent has at least one of an alkaline earth metal carbonate, forming an infiltration layer adjacent to the premixed layer, wherein the infiltration layer has an infiltrant material selected from at least one of an alkaline earth metal carbonate, and subjecting the premixed layer and the infiltration layer to high pressure high temperature conditions.
