    摘要: In this method, aluminization is performed by using thermochemical treatment, and an aluminum donor piece (6) based on metallic aluminum is placed in the vicinity of the surface to be treated (2), prior to said treatment. Preferably, said piece is provided with a thin metal coating (10) that withstands the treatment temperature. The invention is particularly applicable to protecting cooling channels in the blades of a gas turbine.
