  • Patent number: 6087023
    Abstract: The invention provides an improved near net-shape VPS formed multilayered combustion system component having an inner surface consisting of a smooth protective thermal barrier coating, and an outer layer of superalloy capable of withstanding temperatures in excess of 700.degree. C. The invention also includes the method of forming such components by first vacuum plasma spraying a suitable mold with a ceramic top coat, followed by a bond coat and followed by a thick structural layer of superalloy. The mold is then separated from the multilayered structure which results in the desired near net-shape component. Combustor liners and transition ducts of gas turbine engines can be advantageously formed in this manner.
