  • ENVIRONMENTAL BARRIER COATINGS
    Publication number: 20230234895
    Abstract: Environmental barrier coatings including a bondcoat layer including silicon and a rare earth silicate-based hermetic layer and rare earth silicate-based non-hermetic layer are provided. The rare earth silicate-based hermetic layer is deposited on the bondcoat via a thermal spray process and has an elastic modulus ranging from 100 GPa to 180 GPa. The at least one rare earth silicate-based non-hermetic layer is deposited on the rare earth silicate-based hermetic layer and has an elastic modulus ranging from 50 GPa to 100 GPa. Coated gas turbine engine components and methods for coating gas turbine engine components are also provided.

  • CONSUMABLE COATINGS AND METHODS OF PROTECTING A HIGH TEMPERATURE COMPONENT FROM DUST DEPOSITS
    Publication number: 20210324201
    Abstract: A coated component may have a consumable coating that protects the component from dust. A coated component may include a silicon containing substrate defining a substrate surface, a barrier coating on the substrate surface, with the barrier coating defining a barrier surface, and a consumable coating on the barrier surface. The consumable coating may include a ceramic oxide that includes a silicate. A component, such as a component of a turbomachine, may be protected from dust by applying a consumable coating on the component.

  • Method of repairing a turbine nozzle segment in a turbine engine
    Patent number: 9447689
    Abstract: A method for repairing a turbine nozzle having at least one vane disposed between an inner and an outer band. Embodiments of the method can comprise separating the inner band from the outer band and securing a replacement part to the inner band. In one embodiment, the methods accommodate replacement parts that include vanes with a base feature that comprises a non-airfoil shape and that integrates cooling features useful for operation of the turbine nozzle.
