Diphenolic Schiff bases as corrosion inhibitors for aluminium in 0.1 M HCl: Potentiodynamic polarisation and EQCM investigations

A comparative study of the corrosion inhibition of low carbon steel in HCl solution by an imine compound and its cobalt complex

“…According to some researchers [30,37 ] active site blocking effect can understand with shifting in corrosion potentials, and inhibition efficiency is directly related with inhibitor concentration. When the concentration of inhibitor increases, more inhibitor molecules adsorb on the metal thus providing wider surface coverage [ 38 ]. Consequently, the layer formed by the inhibitor molecules makes a barrier for mass and charge transfer for metal dissolution; hence dissolution rate of steel was reduced.…”

Corrosion inhibition of mild steel by bromide-substituted imidazoline in hydrochloric acid

“…The usage of inhibitors is an effective way to protect iron against aggressive media [3][4][5][6]. The corrosion behavior of metal can be controlled by many natural extracts and synthetical compounds such as bamboo leaves [7], henna [8,9], coffee [10], Myrtus communis [11], Schiff bases [12][13][14], pyrimidine [15][16][17], thiazole [18][19][20], and imidazoline [21][22][23][24]. Chemical structures of those functional compounds are often related with O, S, N atoms, and multiple bonds which are all electron-rich groups [25,26].…”

Adsorption behaviour of o-hydroxy acetophenone benzoyl hydrazone on mild steel/hydrochloric acid interface

“…A wide range of studies have investigated the corrosion inhibition of Schiff base compounds for mild steel, copper, zinc and aluminium [8][9][10]. Schiff bases are the condensation products of an amine and a ketone or aldehyde, and have the general formula RC5 5NR.…”
