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 traditional solution used for industrial hard chrome plating is made up of about 250 g/L of CrO 3 and about 2.5 g/L of SO 4 â . In solution, the chrome exists as chromic acid, known as hexavalent chromium. A high current is used, in part to stabilize a thin layer of chromium(+2) at the surface of the plated work.he traditional solution used for industrial hard chrome plating is made up of about 250 g/L of CrO 3 and about 2.5 g/L of SO 4 â .
