The invention relates to a method for depositing an aluminizing coating onto a substrate (10). Said method comprises the following steps: (a) depositing a layer (23), containing platinum and at least 35% of nickel, onto a surface (11) of the substrate (10); and (b) depositing an aluminum coating (40) onto said layer (23). L'invention concerne un procédé de dépôt d'un revêtement d'aluminisation sur un substrat ( 10). Ce procédé comporte les étapes suivantes; (a) On dépose une couche (23) contenant du platine et au moins 35% de nickel sur une surface (11) du substrat (10), (b) On dépose un revêtement d'aluminium (40) sur cette couche (23).
