    摘要： The present invention enables the diamond coating of stationary elongate objects, such as twist drills, with a continuous uniform film without any motion of the twist drill due to the unexpected superb "throwing power" of a reactor disclosed herein. The CVD diamond reactor includes a vacuum chamber, inlet for feed hydrogen/hydrocarbon mixtures, and an outlet, in conventional fashion. The improvement for coating with CVD diamond the entire outer surface of at least a portion of a plurality of stationary elongate objects comprises disposed within said reactor, an elongate metal tube having a plurality of apertures for holding elongate objects disposed radially inwardly and having a cooling pipe in thermal contact with and disposed about the outside of said metal tube; and a filament running within said tube along its lengthwise extent and being in electrical connection with the source of voltage for heating said filament to a temperature adequate to initiate hydrocarbon disassociation, the portions of said elongate object within said tube surrounding said filament being heated thereby.

    摘要： Broadly, the present invention is directed to improving a chemical vapor phase deposition (CVD) method for synthesis of diamond wherein a hydrocarbon/hydrogen gaseous mixture is subjected to a combustion flame in the presence of oxygen to at least partially decompose the gaseous mixture to form CVD diamond. The improvement in process comprises subjecting said combustion flame to one or more of dielectric heating, d.c. discharge, or a.c. discharge. Dielectric heating can be accomplished by subjecting the combustion flame to microwave (MW) frequency discharge or radiofrequency (RF) discharge. By superimposing dielectric heating or d.c./a.c. discharge plasma generation on combustion flame process, the carbon utilization rate of the combustion flame process should improve substantially. As noted above, given the low carbon utilization rate for combustion flame techniques already, small percentage improvements in the carbon utilization rates translate into substantial cost savings in generation of CVD diamond by such combustion flame technique.
