Abstract (en)
The present invention relates to an electrolyte composition for the deposition of a tin-zinc alloy on a substrate surface. Furthermore, the invention relates to a method for the deposition of a tin-zinc alloy layer on the substrate surface. The inventive electrolyte composition for the deposition of a tin-zinc alloy on a substrate surface comprises tin in oxidation state +4(Sn 4+ ) and has a pH-value in the range from about pH 9 to about pH 11. Furthermore, the inventive electrolyte composition can comprise a complexing agent of the group consisting of carboxylates, amino derivates, phosphates and hydroxides as well as brightening agents or surface wetting agents.
