ABSTRACT:
The invention relates to diamond coatings and the growth of diamond coatings suitable for tools, wear parts, and the like. The invention controls process conditions to produce polycrystalline coatings having progressively finer grain size in the direction of the outer surface. This enhances the wear resistance and finish characteristics of the parts and tools. In one process, chemical vapor deposition is used to grow a first region over a substrate with a plurality of nucleation sites and the first region transitions into polycrystalline diamond grains growing progressively smaller to an average grain size of less than three microns.
