Anti-Corrosion Performance of Cr+6-Free Passivating

steel sheets, to be used in food, automotive, appliances, etc. industries, is being extensively explored all over the world. In this sense, the most common transitional alter-native to Cr6+ is Cr3+, which is used since the mid 1970s [3-9]. According to Fonte et al. [10], the Cr3+ conversion layer formed in a bath containing transition metal ions
