Molecular structure, tautomer's, reactivity and inhibition studies on 6-Methyl-2-thiouracil for mild steel corrosion in aqueous HCl (1.00 M): Experimental and Theoretical Studies

Study of the Corrosion of Nickel–Chromium Alloy in an Acidic Solution Protected by Nickel Nanoparticles

“…Polarization curves show that both the anode Tafel slopes (βa) and the cathodic ones (βc) decrease significantly by applying the Ni coating at different pH values, which suggests that Ni coating mainly inhibits both the anodic dissolution of the Ni–Cr alloy and the cathodic hydrogen reduction process to some extent. 36 It is clear that the hydrogen evolution reaction and the metallic dissolution could be controlled, and the mechanism of the proton discharge reaction differed depending on the technique of protection utilized.…”

“…A thin nickel layer coating applied to the Ni–Cr alloy surface in 1 M sulfuric acid solution decreased the cathodic and anodic slopes, suggesting that the hydrogen production mechanisms were affected by applying a thin protective film on the alloy surface. Polarization curves show that both the anode Tafel slopes (βa) and the cathodic ones (βc) decrease significantly by applying the Ni coating at different pH values, which suggests that Ni coating mainly inhibits both the anodic dissolution of the Ni–Cr alloy and the cathodic hydrogen reduction process to some extent .

Anticorrosion Study for Brass Alloys in Heat Exchangers during Acid Cleaning Using Novel Gemini Surfactants Based on Benzalkonium Tetrafluoroborate

“…XPS has been broadly used in the corrosion protection field in recent years to determine the composition of molecular protective films and the bonding of heteroatoms and metals in corrosion inhibitors. , The XPS studies were conducted on the inhibited brass samples pre-exposed to electrolytic conditions for 24 h to examine the interaction of the studied I Me inhibitor molecules with the brass surface. The analyses were carried out in the binding energy (BE) range of Cu 2p, C 1s, and N 1s peaks.…”

Corrosion mitigation for steel in acid environment using novel p-phenylenediamine and benzidine coumarin derivatives: synthesis, electrochemical, computational and SRB biological resistivity

“…3 Electron donation to the d orbital of a metal is easier for organic compounds with available electrons to share located on their double bonds or via hereto atoms and this donation makes organic compounds potential corrosion inhibitors. [4][5][6][7][8] Diethyl(phenyl(phenylamino)methyl)phosphonate (DEPAMP) and diethyl((2-methoxyphenyl)(phenylamino)methyl)phosphonate (o-DEPAMP), when utilized as corrosion inhibitors for XC48 steel in a 1 M HCl solution, yield 89.27% and 90.72% inhibition efficiencies at 10 −3 M, respectively. 9 2,6-Bis(hydroxymethyl)-4methoxyphenol (1) or 4-chloro-2,6-bis(hydroxymethyl)phenol (2) showed 93% and 84% inhibition efficiency at 5 Â 10 −2 M, respectively.…”

“…34,35 Desulfotomaculum and Desulfovibrio strains are the most familiar SRB strains. These strains have a great ability to survive even in aggressive conditions like high pressure (507 bar), high temperature (40 C) and also different pH values (4)(5)(6)(7)(8). 36 Hydrogen sulde gas (H 2 S), sulfate and metal suldes are the most commonly generated products for SRB via an oxidation-reduction mechanism.…”
