  • 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.

  • Method of producing protective coatings with chemical composition and structure gradient across the thickness
    Patent number: 5834070
    Abstract: The invention relates to the production of protective coatings for parts of gas turbines and internal combustion engines which are to be subjected to thermal loading. A coating formed in accordance with the invention has a chemical composition and structure gradient across its thickness and an outer ceramic layer. The coating is obtained by electron beam heating of a mixture of metals (alloys) and oxides which have different vapor pressures at the evaporation temperature, the mixture and an underlying ceramic ingot being serially evaporated and subsequently condensed on the part to be coated.
