    摘要： In its broadest aspects, the present invention is directed to a method for improving the abrasion resistance of the annular interior surface of an annulus. Such method comprises the steps of (a) placing said annulus heated to an elevated CVD diamond-forming temperature in a vacuum chamber held under reduced pressure; (b) providing a hydrocarbon/hydrogen gaseous mixture within said chamber; (c) at least partially decomposing said gaseous mixture in said chamber; and (d) directing said at least partially decomposed gaseous mixture into said heated annular interior for diamond deposition/growth to occur on said annular interior surface. As noted above, spray nozzles, valves, injectors, wire drawing dies, and like annular products are ideally suited for use in accordance with the precepts of the present invention.

    摘要： The present invention relates to a method for growing diamond on a diamond substrate by chemical vapor deposition. The inventive method comprises alternatingly contacting at elevated temperature said diamond substrate with a gas having the formula C.sub.n X.sub.m and then with a gas having the formula C.sub.l Z.sub.p. X and Z each form single bonds with carbon. X and Z also are reactable to form ZX or a derivative thereof. The Z--X bond is stronger than the C--X bond and also is stronger than the C--Z bond. In the formulas, n, m, l, and p are integers. If C.sub.n X.sub.m and C.sub.l Z.sub.p do not react in the gas phase, then a gas mixture of them can be used to grow diamond instead of the alternating exposure of one and then the other.

    摘要： A carbon chalcogenide macromolecular composition prepared from carbon dichalcogenide and to a process for the preparation thereof. A carbon dichalcogenide, for example, carbon disulfide, in entrained in an inert gas, and the mixture formed therefrom is passed over a hot tungsten filament wherein carbon disulfide is degraded into fragments. The fragments are then deposited onto a surface of a non-reactive substrate. The deposited fragments recombine to form the macromolecular composition. A significant characteristic of the composition is its threshold voltage above which its electrical resistance drops precipitously. This characteristic also exhibits a unique temperature dependence. Dopants may be added to the composition to reduce the electrical resistance.

    摘要： Broadly, the present invention is directed to polycrystalline diamond of improved thermal conductivity. The novel polycrystalline diamond consists essentially of at least 99.5 wt-% isotopically-pure carbon-12 or carbon-13. The inventive polycrystalline diamond is formed from at least 99.5 wt-% isotopically-pure carbon-12 or carbon-13. Single-crystal isotopically-pure carbon-12 and carbon-13 diamond are known to possess improved thermal conductivity. Polycrystalline diamond, however, possesses lower thermal conductivity patterns deleteriously impacted by, for example, impurities, isotopic effects, and grain boundary scattering. In fact, grain boundary scattering would lead the skilled artisan to believe that the thermal conductivity of polycrystalline diamond would be substantially unaffected by the isotopic nature of the diamond itself. Unexpectedly, however, isotopic effects were discovered to predominate in impacting the thermal conductivity of polycrystalline diamond consisting essentially of isotopically-pure carbon-12 or carbon-13. This is true whether the isotopically-pure polycrystalline diamond is grown directly or whether individual isotopically-pure carbon-12 or carbon 13 diamond crystals are subjected to sintering for forming a polycrystalline structure, e.g. layer or compact, thereof.
