Patent ID: 8202574

Claim:
An aluminization process by vapor phase deposition for high-temperature oxidation protection of a metal turbomachine part, the process comprising: introducing a nozzle guide vane including a hollow blade provided between a first platform and a second platform, a cavity of the hollow blade communicating with a first opening provided in the first platform and with a second opening provided in the second platform; surface-enriching a perforated liner of substantially cylindrical shape with aluminum in order to serve as an aluminum donor; inserting the liner inside the cavity of the hollow blade through the first opening; attaching an upper edge of the liner to an upper edge of the cavity of the hollow blade while leaving a lower edge of the liner free; forming a halide by reaction between a halogen and the liner containing aluminum; and transporting the halide by a carrier gas in order to come into contact with said guide vane so as to aluminize surfaces of the cavity of the hollow blade.
