To this end, the AA2024 alloy was immersed in NaCl solution (50 mM) with different TA concentrations (0.1–10 mM) for 7 days. Surface (SEM, Raman, and SKPFM) and electrochemical analyses (EIS, PDP, and SVET) revealed mixed inhibition after 1 day of immersion in TA solution. Long-term immersion tests in TA solutions produced a tannate-rich oxide film on the surface. The films with low tannate content (formed in 0.1 and 1 mM TA) showed the highest stability and corrosion resistance.engAttribution-NonCommercial-ShareAlike 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-sa/4.0/datasethttps://doi.org/10.1016/j.apsusc.2024.161434open access6202024AluminiumTannic acidCorrosion inhibitorEco-friendlyGreen inhibitionMateriales3312 Tecnología de Materiales
