Chromate conversion coatings are produced on various metals by immersion or electrochemical treatment with chromates along with other chemicals. These coatings provide exceptionally good corrosion resistance, depending upon the composition of chemicals and the film thickness. Additionally chromating brightens zinc and cadmium electrodeposits and also improves paint bonding. Chromatising on zinc deposits produces different coloured finishes from clear blue bright, yellow iridescent, black and olive green which have different corrosion resistant properties.
