Abstract

Bains de dépôt électrolytique de rhodium et composition les renfermant. Ces bains aqueux acides de revêtement de rhodium comprennent 0,1 à 30 g/l d'ions rhodium, 0,1 à 20 g/l d'un acide carboxylique organique polycarboxylique, contenant au moins un groupe amino, et 10 à 100 g/l de radicaux orthophosphates, le bain ayant un pH de 0,1 à 2,0. La presente invention est particulièrement utile pour fournir des bains de revêtement de rhodium où la teneur en rhodium est maintenue à une faible valeur, tout en fournissant un dépôt électrolytique brillant.Rhodium electrolytic deposition baths and composition containing them. These acidic aqueous rhodium coating baths comprise 0.1 to 30 g / l of rhodium ions, 0.1 to 20 g / l of an organic polycarboxylic carboxylic acid, containing at least one amino group, and 10 to 100 g / l of orthophosphate radicals, the bath having a pH of 0.1 to 2.0. The present invention is particularly useful for providing rhodium coating baths where the rhodium content is kept low, while providing a bright electroplate.
