Title: The Innovator Behind Cutting-Edge Diamond Technologies: Louis K Bigelow
Introduction
Louis K Bigelow, an accomplished inventor based in Salt Lake City, UT, holds an impressive portfolio of 16 patents. His innovative spirit and dedication to advancing technology have significantly impacted the field of diamond materials, particularly in applications related to cutting tools and thermal conductivity.
Latest Patents
Among his latest contributions to the industry is a groundbreaking method of making white diamond film. This technology involves depositing a diamond film with negligible non-diamond carbon and high thermal conductivity using a specialized direct current arc jet apparatus. The process operates at a substrate temperature below approximately 975 degrees Celsius, with an arc power ranging between 20 and 40 kW. Furthermore, it requires a pressure of around 12 torr and an enthalpy surpassing 30 from an activated gas jet composed of hydrogen and methane, which is supplied at a concentration of less than 0.07%. The resulting diamond material is noted for its exceptional transparency and thermal conductivity, making it highly suitable for cutting tool applications, especially in milling.
Another notable invention by Bigelow is related to the brazing of diamond film to tungsten carbide. In this patent, the reliability of the braze joint is enhanced through the use of a vanadium-containing braze. Remarkably, the braze joint displays an average shear strength exceeding 40,000 pounds per square inch (276 MPa), and the contact angle with the diamond film is less than 15 degrees, denoting an efficient bonding capability.
