Abstract
A process for coating an aluminum article with zinc by immersing the article in an aqueous bath prepared by dissolving solid zinc fluoride in water. Preferably, the pH of the bath is about 4 to about 6. After coating, the article can be heated to diffuse zinc into surface-adjacent regions of the article and thereby to provide a zinc-diffused layer that protects the article against corrosion.
