Process was developed for free-chromate passivation of zinc coatings. An optimal composition of the solution was developed. It was shown that titanium-based passivating coatings on the electrogalvanized steel articles compare well in corrosion resistance and protecting capacity with iridescent chromate coatings. It was revealed that, unlike chromate coatings, the developed titanium-based coatings withstand the thermal shock without degrading of characteristics.Keywords: Corrosion protection, conversion coatings, Ti-based coatings, chromate-free passivation
