Electrophoretic deposition of boehmite particles to improve the anti-corrosion behavior of anodized aluminum alloy 2024-T3

Abstract : The purpose of this study was to prepare and evaluate a new two-step sealing process for a porous and tortuous anodic film, prepared on aluminum alloy (AA) 2024-T3, to ensure anti-corrosion properties. This process involves a cathodic electrophoretic deposition of boehmite particles, followed by a hydrothermal post-treatment. This two-step sealing was evaluated through three industrial tests (dye-spot, continuity and salt spray) and the low frequency resistance. Such sealing of the anodic film on AA 2024-T3 showed promising anti-corrosion behavior, suggesting a real potential interest of this innovative process for future industrial applications.
