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.
The limitations of zinc are that when the plating begins to corrode the zinc rust is plentiful and unsightly. Zinc Plating is available in clear (silver color), blue, yellow, black and olive drab green. Trivalant chromates are used if requested.inc Nickel was also developed as a cadmium replacement. Amazing corrosion resistance and its ability to handle high temperatures is making this plating very popular with all the automotive companies. Zinc Nickel can withstand from 1000 to 2000 hours of salt spray testing.
