Overview

The study demonstrates enhanced corrosion resistance in AA2024-T3 aluminum alloy, indicating effective anodizing with carboxylic acids.

Key Points

The aim is to investigate how different carboxylic acids in anodizing electrolytes affect the corrosion resistance of AA2024-T3 aluminum alloy.
Characterization of anodic oxide films using microscopy and electrochemical analyses.
Evaluation of surface morphology and corrosion resistance in 0.1 mol.L-1 NaCl solution.
Comparison of results between treatments with different carboxylic acids and standard sulfuric acid.
Formation of oxide films with uniform thickness between 16.7 to 23.8 µm.
Oxalic acid treatment resulted in the highest corrosion protection after 21 days of immersion.
Other carboxylic acids (citric and succinic) displayed lower protective performance compared to oxalic acid.
