Zinc plating in general can be broken into two primary steps.

It is used industrially in chromate conversion coatings having been developed by the ford motor company in the 1920s. Even today chromate finishes including zinc chromate provide superior corrosion resistance. However the coating color can also be changed with dyes so color is not a complete indicator of the process used. The first step is to add the zinc plating through the use of electrical current.

Zinc chromate zn cr o 4 is a chemical compound containing the chromate anion appearing as odorless yellow powder or yellow green crystals but when used for coatings pigments are often added. Additionally zinc chromate is highly toxic thus protecting the surface from proliferation of organic matter. The protective effect of chromate coatings on zinc is indicated by color progressing from clear blue to yellow gold olive drab and black. Zinc chromate is a corrosion resistant agent that is added to certain coatings.
