Method for aluminising a metal part of a turbomachine in vapour phase

摘要

A metal turbomachine portion comprises a cavity into which a metal component is introduced and assembled from an opening in portion. Halide is formed by reaction between a halogen and a metal donor containing aluminum. Halide is transported by a carrier gas in order to contact with metal portion. The metal component is surface-enriched with aluminum in order to serve as an aluminum donor, before the implementation of process. Thus, aluminization by vapor phase deposition for high-temperature oxidation protection of metal turbomachine portion is carried out. Independent claims are included for the following: (1) liner for distributing cooling air; (2) hollow turbomachine vane; and (3) turbomachine nozzle.
