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.
Widely used by industry in general, and automotive manufacturers in particular, zinc nickel gives sacrificial protection to the underlying iron or steel, that is the zinc corrodes in preference to the substrate.his ensures that use in engine bays and in contact with hot oil does not reduce corrosion resistance.When a silver coating is required, enhanced corrosion resistance can be obtained by using the seals or lacquers.The zinc nickel solution used has the following advantages over zinc electro plating.1.
