Claim:
1. A process for electrolytically depositing a layer of a tin- and ruthenium-based alloy on a cathode soaked into an aqueous electrolytic bath, comprising: providing, in said aqueous electrolytic bath, at least: tin in an amount comprised between 1 and 100 g/L of electrolytic bath; ruthenium in an amount comprised between 0.030 and 10 g/L of electrolytic bath; one or more conductor salts in an amount comprised between 5 and 100 g/L of electrolytic bath; complex forming salts in an amount comprised between 10 and 100 g/L of electrolytic bath; and alkali metal hydroxides in an amount comprised between 0.2 and 10 g/L of electrolytic bath; wherein, in said electrolytic bath, are absent; and electrolytically depositing the layer of the tin- and ruthenium based alloy on the cathode soaked in the aqueous electrolytic bath.
