Abstract
A corrosion-inhibiting coating, process, and system that provides a tight, adherent zinc- or zinc-alloy coating that is directly deposited onto steel or cast iron surfaces for enhanced corrosion protection. A process for applying the coating is also provided. The process includes the application of two sequential aqueous baths. The first bath contains a precursor zinc compound while the second bath contains a reducing agent to deposit the zinc directly upon the steel or cast iron.
