| Abstract: | In this paper,to replace the traditional highly toxic chromate passivation,I researched the chromium-free passivation technology of the galvanized sheet,and choosed molybdate as the main component to study the galvanized steel passivation technology systematically.I discussed the temperature of passivation,the time of passivation,the pH value of passivation to study the impact of the passive film and corrosion resistance.The corrosion resistance of samples with Chromium-free passivation was studied using te... |
