Abstract (en)
[origin: EP2230331A1] The galvanic process of deposition of an anthracite color coating for metal parts, comprises initially depositing a gold-nickel alloy on the metal parts using an electrolytic bath, and processing the gold-nickel alloy using a diluted acid bath. The acid bath is diluted using 1-50 ml/l of concentrated acid, and contains a wetting product. An independent claim is included for metal parts with an anthracite color coating.
