An aluminization process by vapor phase deposition for high-temperature oxidation protection of a metal turbomachine part. The part including a cavity into which a metal component is introduced and assembled from an opening in the part. A halide is formed by reaction between a halogen and a metal donor containing aluminum, then the halide is transported by a carrier gas in order to come into contact with the metal part, wherein the metal component has first, before the implementation of the process, been surface-enriched with aluminum in order to serve as an aluminum donor.

Process for the vapor phase aluminization of a turbomachine metal part and donor liner and turbomachine vane comprising such a liner

A method of aluminization by deposit in the vapor phase for protection against oxidation at high temperature of a metal part of a turbomachine. The part includes a cavity with an opening that can be accessed from the outside. A halide is formed by reaction between a halogen and a metal donor containing aluminum, then the halide is transported by a carrier gas to come into contact with the metal part, the metal donor being placed at least partly in the cavity. The metal donor is in the form of a pellet obtained by hot sintering under pressure of a mixture of metal powder.
