Paper Title:
Electrochemical Properties of Anodized and Sealed Aluminum Films
  Abstract

The electrochemical behaviors of anodized and sealed aluminum alloys in NaCl solution were studied by potentiodynamic polarization, the open-circuit-potential and EIS. The results show that anodic oxidization of aluminum increases its corrosion resistance greatly. Different sealing methods have different influences on corrosion behavior of the anodized alloys in NaCl solution; corrosion resistance increases in the order: no sealing < water sealing < dichromate sealing < nickel fluoride sealing. The modulus of the porous film sealed by dichromate solution increases with the immersion time in NaCl solution, which is similar to the self-sealing effect of unsealed anodic films.
