ABSTRACT:
Markedly superior corrosion protective properties are imparted to metal-bearing surfaces at substantially reduced costs by depositing upon said surfaces one or more superimposed coatings containing zinc alloying elements located intermediate the metal-bearing surfaces and a sacrificial layer of generally pure zinc. In this manner penetration of rust inducing substances into the metal bearing surfaces is effectively precluded under substantially all environmental conditions normally encountered.
