Abstract

La présente invention concerne un procédé de formation d'un revêtement par diffusion d'un métal protecteur sur une pièce de métal ou d'alliage métallique. Selon ce procédé on effectue les étapes suivantes : revêtement de la pièce par une composition de revêtement comprenant une suspension du métal protecteur dans un véhicule liquide, puis traitement thermique de la pièce revêtue dans une atmosphère non oxydante, pour provoquer la diffusion du métal protecteur dans la surface de pièce. Ce procédé permet de revêtir en particulier les surfaces internes de cavités présentant une ouverture d'accès très étroite.
