Abstract

The present invention provides a passivation formulation and a process for forming trivalent chromium-based passivation film on zinc and zinc alloys. The passivation film incorporates nano-ceramic particles resulting in higher corrosion resistance as compared to a trivalent chromium passivation film without nano-sized ceramic particles. The corrosion resistance of the coating is further enhanced by a topcoat or a sealant
