Abstract

A two-step process for coating a surface of an aluminum article with zinc, wherein the surface is initially exposed to a zincate bath under relatively weak zinc-depositing conditions, and then further exposed to a zincate bath under stronger zinc-depositing conditions (lower ZnO concentration and/or higher temperature), to establish thereon an adherent coating of metallic zinc. The coated article may be heated to effect diffusion of the zinc into the aluminum for producing a zinc-enriched region adjacent the surface to protect the surface against corrosion.
