ABSTRACT:
A repair process for repairing damaged turbine air seals comprises completely removing the damaged air seals and forming a mechanical seat in the seal base. A replacement ring of the desired seal alloy is positioned in the seat and bonded to the base by a brazing process. The replacement ring is then machined to form reconstructed knife edge seals.
