Abstract

Protection contre la corrosion galvanique d’assemblage de pièces métalliques Assemblage (10, 100, 200) d’un élément métallique (20, 120, 210) comprenant de l’acier inoxydable et d’une pièce métallique (60, 140, 220) comprenant un matériau différent de l’acier inoxydable, caractérisé en ce que l’élément métallique (20, 120, 210) comprenant de l’acier inoxydable et la pièce métallique (60, 140, 220) sont isolés l’un de l’autre par une pièce intercalaire (30, 130, 230) comprenant un substrat (40) en acier recouvert d’un revêtement métallique (50) en alliage de zinc, l’alliage comprenant de l’aluminium et du magnésium.
