摘要：
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.
