Abstract
L'invention concerne l'électrodéposition de palladium sur des substrats. Elle se rapporte à un procédé qui comprend la circulation d'un courant électrique entre une anode et des substrats dans un bain comprenant une solution aqueuse de dinitrite de diammonium et de palladium et de pyrophosphate tétrapotassique. La densité de courant dans le bain est avantageusement de 0,2 à 5,4 A/dm**2 et le pH est avantageusement compris entre 8,5 et 11. Application à l'électrodéposition du palladium sur des substrats métalliques.
