Sealing Effect of KAl(SO4)2 Solution on the Corrosion Resistance of Anodized Aluminum Alloy
文献摘要：
The 2024 anodized aluminum alloy film was sealed by KAl(SO4)2 solution and the effect of sealing on corrosion resistance was investigated by means of potentiodynamic polarization curves, electrochemical impedance spectroscopy, and X-ray photoelectron spectroscopy. The experimental results show that the optimal parameters for KAl(SO4)2 sealing are 35 ℃, with the pH value of 8, the concentration of 8 g/L, and the sealing time of 3 min. The corrosion resistance of the KAl(SO4)2 sealed sample can be significantly improved than that of unsealed one, and is obviously superior to that of the conventional hydrothermal sealed sample. Furthermore, X-ray photoelectron spectroscopy demonstrates that more Al(OH)3 will be formed in the process of KAl(SO4)2 sealing, which will shrink the diameter of the microporous and therefore results in the excellent corrosion resistance.
