ABSTRACT:
Metals and alloys of metals which have the property of electrolytic rectification can be coated with an anticorrosive coating by immersion in a strongly alkaline aqueous bath comprising a water soluble fluoride, a water soluble iron salt, and mixtures thereof by the application of a sufficiently high voltage to obtain spark discharge at the surface to be coated, said potential being applied between the metal or alloy to be coated utilized as an anode and a cathode immersed in the aqueous bath. A durable coating is thereby applied to the surface of said metals or alloys thereof which is resistant to a corrosive salt spray environment.
