With a total of 7 patents to his name, Undercoffer's work has had a substantial impact on various industrial applications.
Latest Patents
One of his latest patents is the MT CVD process, which involves a method for coating substrates with a carbonitride-containing coating. This process includes heating substrates to a reaction temperature in a reaction chamber and introducing a deposition process gas that contains a hydrogen halide and predetermined amounts of carbon/nitrogen sources, metal-halogen compounds, and hydrogen. The method allows for the deposition of a layer of carbonitride-containing coating on the substrate surfaces. Additionally, the invention includes methods for maintaining a temperature gradient in the reaction chamber during the gas introduction. The coatings produced can include carbonitrides, oxycarbonitrides, and borocarbonitrides of various metals.
Another significant patent involves coated cutting tools, which feature a coating and a substrate. The coating consists of at least one CVD layer that may exhibit residual tensile stress, along with at least one layer that has a high residual compressive stress. The outermost layer is designed to contain these compressive stresses, enhancing the tool's performance. The substrate is a composite material that incorporates hard refractory grains, making it suitable for demanding cutting applications.
