ABSTRACT:
A method for producing a corrosion-resistant article exhibiting low hydrogen embrittlement, comprising electroplating the article with a zinc-nickel alloy. The zinc-nickel alloy is plated from an aqueous acidic plating solution containing zinc, nickel, an electrolyte in the form of a soluble ammonium salt, and a polyoxyalkylated nonionic surfactant. The bath can also contain an anionic surfactant, a buffer such as boric acid, and a brightener.
