Introduction
Robert H. Cummings is a notable inventor based in Santa Clara, CA. He has made significant contributions to the field of manufacturing, particularly in the development of advanced materials. With a total of two patents to his name, Cummings has focused on enhancing the performance of cemented tungsten carbide substrates.
Latest Patents
Cummings' latest patents include innovative methods for creating cemented tungsten carbide substrates with adherent diamond films. The first patent describes a process that prepares the substrate surface by removing a small amount of tungsten carbide while preserving the cobalt binder. This is achieved using Murakami's reagent. Following this, any remaining residue is eliminated using a solution of sulfuric acid and hydrogen peroxide. The resulting diamond-coated cemented tungsten carbide tool can be formed using an unpolished substrate, which may be prepared through etching. The deposition of a continuous diamond film can be accomplished through various techniques, including reactive vapor deposition and plasma-enhanced CVD.
The second patent mirrors the first in its focus on methods for coating adherent diamond films on cemented tungsten carbide. The processes outlined are similar, emphasizing the importance of substrate preparation and the techniques used for diamond film deposition.
