abstract = {The corrosion protection effect of aromatic carboxylates (benzoate, phthalate, isophthalate, terephthalate, 1,2,4-benzoate, trimesate, and 1,2,4,5-benzenetetracarboxylate) in NaCl solution on AZ31 alloy has been investigated. The results reveal that the inhibition mechanism is attributed to the effect of the studied molecules on the protective properties of a thin inhibitor-Mg(OH)2/MgO layer formed on the Mg surface. Both the number and position of carboxylate groups on the benzene ring influence the inhibition efficiencies of these inhibitors. A flat-lying molecular configuration more effectively shields the Mg surface from corrosive media. The findings confirm that the inhibitor-stabilized Mg(OH)2/MgO layer effectively blocks Cl- ingress and ensures strong corrosion protection for AZ31 alloy.}
