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.
