ABSTRACT:
A process for simultaneously cementing diamond fines together and bonding the cemented diamonds to a silicon-silicon carbide composite is described. During the process the silicon-silicon-carbide composite furnishes silicon for the cementing and bonding function and the silicon-silicon carbide composite provides for the structural stability of the resulting article. The process comprises placing a quantity of diamond powder and a mass of silicon-silicon carbide composite adjacent to each other, packing such material to form a stabilized geometry, heating the stabilized geometry in an inert atmosphere, and simultaneously applying pressure thereto.
