Abstract

Bain exempt de citrate pour le dépot électrolytique d'alliages d'or à grande vitesse sur des substrats, qui comprend une source d'or (par exemple du cyanure d'or (I) et de potassium), une source de métal d'alliage (par exemple du sulfate de nickel), de l'acide oxalique et de l'acide formique. En raison de l'absence de citrate, de plus grandes vitesses de dépot sont obtenues et la précipitation de certains citrates salins (par exemple le citrate de nickel) est évitée.Citrate-free bath for the electrolytic deposition of high-speed gold alloys on substrates, which includes a source of gold (e.g. gold (I) and potassium cyanide), a source of metal alloy (eg nickel sulfate), oxalic acid and formic acid. Due to the absence of citrate, higher deposition rates are obtained and the precipitation of certain saline citrates (for example nickel citrate) is avoided.
