ABSTRACT:
Disclosed is an improved polycrystalline compact of self-bonded diamond particles having a network of interconnected empty pores dispersed throughout. The improved porous polycrystalline diamond compact possesses enhanced oxidation resistance and comprises all of the exterior surfaces of the porous compact being enveloped with a continuous coating which is effective under metal bond fabrication conditions so that oxidation of the diamond in the compact does not exceed a threshold level whereat loss of diamond properties of the compact occurs. Metal bond fabrication conditions comprehend an atmosphere containing oxygen or water vapor. Metal coatings are preferred, especially in coating thicknesses in excess of about 8 microns, and applied by a chemical vapor deposition process.
