ONEEBODY COMPOSITE BODY OF POLYCRYSTAL DIAMOND AND*OR CUBIC BORON NITRIDE PHASE AND SUBSTRATE PHASE

摘要

A shaped confined structure composed of a mass of diamond and/or cubic boron nitride crystals coated with elemental non-diamond carbon in contact with a carbonaceous substrate is infiltrated by fluid silicon producing a like-shaped composite of a polycrystalline body phase integrally bonded to a substrate supporting phase.
