A&P here. Zinc chromate is used as a primer on aluminum surfaces as a conversion process to inhibit corrosion. Since nearly all modern aircraft skins and structures are made from aluminum, this compound and its derivatives are the most common primers seen in aircraft manufacturing.
Zinc-iron-Zinc-cobalt-Zinc-nickel and Tin-zinc. Except for the latter, zinc accounts for 85-99% of the alloy composition. As in zinc plating, chromate conversion coating as a post treatment is important in improving the overall corrosion resistance of zinc alloys.a) Salt Spray Test-The salt spray test has been used to assess the protective value of zinc and cadmium coatings however the results do not correlate with any given service exposure.
