Latest Patents

The supplied information lists 1 patent for Liang Guo: “Method for Making a Highly Stable Diamond Film on a Substrate.” The invention describes pretreating a metal substrate and depositing diamond through multiple chemical vapor deposition stages, with each successive stage conducted at a higher temperature. The diamond may be boron-doped, and suitable substrates include titanium, titanium alloys, iron, iron alloys, and other valve metals.

The process may include an initial stage that forms a carbide layer between the substrate and diamond. A mixture of diamond and amorphous carbon may then help bond that layer to a later deposit. The resulting material is described as suitable for use in electrodes, cutting-tool teeth or blades, and other applications.
