Zinc plating is a soft, ductile, decorative,
corrosion-resistant finish. Unlike most other commonly plated metals, zinc
protects the substrate by sacrificing itself and thus corrodes before the base
metal. For corrosion protection, chromates are applied over the zinc. Chromates
are chemical conversion coatings. The substrate metal participates in the
coating reaction and becomes a component of the coating. The collaboration has a
profound effect on the properties of the coating. Chromate films are typically
very thin, on the order of .0000001" and contribute no measurable thickness to
the overall coating.
