Abstract
In one embodiment of the present invention, a method of fabricating a superabrasive article is disclosed. A mass of unsintered diamond particles may be infiltrated with metal-solvent catalyst from a metal-solvent-catalyst-containing material to promote formation of a sintered body of diamond grains including interstitial regions. At least a portion of the interstitial regions may also be infiltrated with silicon from a silicon-containing material. The silicon reacts with the sintered body to form silicon carbide within a portion of the interstitial regions.
