| Abstract: | To improve the corrosion resistance of trivalent chromium coatings,trivalent chromium-zirconium hybrid coatings were prepared on 6063 aluminum alloy by using chromic potassium sulfate and zirconium sulfate,and phosphoric acid.Polarization curves and electrochemical impedance spectroscopy(EIS)were used to investigate the electrochemical characteristics of chromium-zirconium hybrid coatings formed in plating solutions of different concentrations of zirconium sulfate,and better corrosion resistance was confirm... |
