dc.description.abstractThis study introduces an innovative passivation technique designed to improve the corrosion resistance of zinc coatings. The impact of varying sodium silicate concentrations (4, 6, and 8 mL/L) and passivation times (30-90 s) was examined in baths containing Cr+3 and Co+3 ions. The 120-h salt spray test results revealed that the optimal corrosion resistance was achieved with a medium sodium silicate concentration of 6 mL/L and a 30-s passivation time. This combination led to a significant improvement in performance, with only 12% white rust observed after 120 h. The study highlights the importance of optimizing treatment parameters to significantly enhance corrosion resistance. Notably, Simonkolleit was obtained at a high concentration of 6 mL/L and a 30-s passivation time, further contributing to the enhanced durability of the coating. These surface enhancements provide a promising approach for achieving durable and more efficient zinc coatings in industrial applications.
