Mn-based species were successfully incorporated into the Ca-Al-LDH structure by a low-temperature post-treatment (Ca-Al-LDH-Mn). Both LDH coatings disclosed a flaky-like morphology and low thickness (~0.6 µm). Ca-Al-LDH-Mn coating showed optimal paint adhesion and the highest long-term corrosion resistance in 3.5 wt% NaCl solution. Evaluation of scribed LDH specimens by SEM/EDS techniques up to 7 days of immersion in 3.5 wt% NaCl solution revealed that the presence of Mn species in the Ca-Al-LDH-Mn provided active corrosion protection. eng http://creativecommons.org/licenses/by-nc-sa/4.0/ open access Attribution-NonCommercial-ShareAlike 4.0 International Data: Permanganate loaded Ca-Al-LDH coating for active corrosion protection of 2024-T3 alloy dataset
