    摘要: The present invention is a process for applying oxide paint as a touch-up paint for an oxide-based corrosion inhibiting coating with at least one imperfection region. Such oxide-based corrosion inhibiting coatings are applied on superalloy components used for moderately high temperature applications, such as the superalloy components found in the high-pressure turbine (HPT) section of a gas turbine engine, including turbine disks and seals. However, during the application of oxide-based corrosion inhibiting coatings, imperfection regions sometimes occur, exposing the superalloy substrate beneath the oxide-based corrosion inhibiting coating. Such imperfection regions can include a spalled region, a scratched region, a chipped region, an uncoated region, or combinations thereof. The process of the present invention is useful where aircraft engine components have been treated with a corrosion inhibiting three-layer paint oxide system comprising chromia and alumina, but where a small imperfection region or regions within the layer oxide system are present after initial manufacture, refurbishment, or repair of the component.

    摘要: A composition comprising a particulate corrosion resistant component, and a glass-forming binder component. The particulate corrosion resistant component comprises from 0 to about 95% alumina particulates, and from about 5 to 100% corrosion resistant non-alumina particulates having a CTE greater than that of the alumina particulates. Also disclosed is an article comprising a turbine component comprising a metal substrate and a corrosion resistant coating having thickness up to about 10 mils (254 microns) overlaying the metal substrate. At least the layer of this coating adjacent to the metal substrate comprises a glass-forming binder component and the particulate corrosion resistant component adhered to the glass-forming binder component. Further disclosed is a method comprising the following steps: (a) providing a turbine component comprising the metal substrate; (b) depositing on the metal substrate a corrosion resistant coating composition; and (c) curing the deposited corrosion resistant coating composition to form at least one layer of a corrosion resistant coating having a thickness up to about 10 mils (254 microns).
