Both electrogalvanized and hot-dip galvanized steel sheets have been finally produced via organic-inorganic composite coating on the zinc surface to enhance corrosion resistance and afford additional functional properties. New anti-corrosive coating solutions as a chromate alternative comprise of polymer resin and inorganic corrosion inhibitors as an aqueous formulation. In this paper we have prepared anticorrosive organic-inorganic composite solutions and studied anticorrosive ability for the inorganic inhibitors containing both silicate and organo-titanates. The electrogalvanized steel sheets with these coating solutions exhibit excellent corrosion-preventative properties compared to conventional chromate-treated steel sheets. Advanced quality performances of coated steel sheets will be discuss in detail.
