“…The thiol function is supposed to be effective in the action of L ‐Cys. Indeed, sulfur is known to strongly adsorb and interact with a metal surface through its electron‐donating ability, as evidenced by the inhibition of iron by organic sulfides in acidic media 53. In the concept of absolute hardness η , developed by Parr and Pearson,54 the covalent bonding is dominant for a soft acid–soft base combination ( η A = η B ).…”

Various α-amino acid (αAA) molecules were screened for their ability to retard the corrosion of AA2024 aluminum alloy substrate. The αAAs screened were L-arginine (L-Arg), Lasparagine (L-Asn), L-cysteine (L-Cys), L-cystine, L-histidine (L-His), L-methionine (L-Met), L-phenylalanine (L-Phe), L-serine (L-ser), Ltryptophan (L-Trp), and L-tyrosine (L-Tyr). From their performances compared with that of the reference additives chromate and 2-mercaptobenzothiazolate (MBT), L-Cys and L-Phe were selected, and their layered double hydroxide (LDH) interleaved derivatives were further scrutinized. Different LDH phases, namely, LiAl 2 , Mg 2 Al, MgZnAl, and Zn 2 Al, were tested as hosts for the inhibitor αAA substances, and the materials were characterized by XRD, FTIR spectroscopy, and SEM. The efficiencies [a]

“…Indeed, Chetouani et al [29,30] have reported the importance of sulphur atom in the drastic change of adsorption mechanism. Furthermore, Brandt et al [31] reported that the sulphur atom represents the active centre of aliphatic sulphides in their interaction with the metal surface.…”

Abstract1-(3-methyl-4H-1,4-benzothiazin-2-yl)ethanone (1,4-BT) was synthesised via a new mechanism. 1,4-BT was thereafter tested as corrosion inhibitor of mild steel in hydrochloric solution at 293 K by weight loss measurements and electrochemical techniques (potentiodynamic polarisation, polarisation resistance, impedance spectroscopy (EIS)). Inhibiting efficiency (E%) increased with concentration and reached highest values up to 98% even at low concentration with changing the mechanism of the corrosion process. Results obtained showed that the inhibitor studied was an efficient inhibitor, especially in cathodic domain. The temperature effect on the corrosion behaviour of mild steel in 1 M HCl with and without 1,4-BT at 5 10 -3 M was studied in the temperature range from 293 to 333 K. E% remains the same even at high temperature. The adsorption free energy and activation parameters for the mild steel dissolution reaction, in the presence of 1,4-BT, were determined. 1,4-BT is adsorbed on the mild steel surface according to a Langmuir isotherm adsorption model.
