Leonila M. Nerodenko has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for producing by evaporation a functionally graded coating with an outer ceramic layer on a metal substrate
    Patent number: 6669989
    Abstract: The invention relates to a method and apparatus for the production of protective coatings on parts. A coating formed in accordance with the invention has a chemical composition and structure gradient across its thickness. The coating is obtained by heating of a composite ingot including a body and at least one insert disposed within the body. As the composite ingot is heated it sequentially evaporates to produce a vapor with a chemical composition varying over the evaporation time period. The composition of the body and composition and location of the insert within the body function to determine the chemical composition of the vapor at any time. Condensation and/or deposition of the vapor onto a substrate forms the inventive coating.
