摘要

Electrogalvanized steel samples have been treated in a solution containing molybdate, phosphate and silicate and in the same solution containing silane and nitric acid as additives. The corrosion resistance of the treated samples has been compared to that of bare samples after exposure to 0.5 N NaCl for 24 h using polarization curves and EIS data. The chemical composition of the coating layers has been determined using different surface analysis techniques. The samples have also been exposed to the salt spray test. The results of these tests suggest that the MPSS treatment is a promising candidate for replacing conventional chro-mate treatments.
