1. Zinc yellow-chromate plated refers to a form of zinc plating in which chromate with a high trivalent or hexavalent chromium content is applied to the surface of a part after it has been plated with zinc12345. This compound prevents the zinc from corroding and produces a yellow-colored finish13. The finish provides a rainbow or iridescent appearance with dominant yellow tones3. This finish is also known as zinc plating, zinc chromate or dichromate4.
