Abstract
A process for non-continuous galvanization of a metal object with a Zn—Al alloy including the steps of pre-coating the object with a metallic layer of sufficient thickness to protect the object from oxidation and yet sufficiently thin to permit the pre-coating to substantially completely react with or dissolve in the molten Zn—Al bath, subjecting the precoated object to a surface activation treatment by immersing it in hydrochloric acid and thereafter allowing the surface to dry with a protective coating of a chloride salt, and thereafter immersing the object in the Zn—Al bath.
