ABSTRACT:
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.
