“…Using ILs for anticorrosion applications has recently attracted researchers’ attention. Among them, using quaternary ammonium salt-based ILs for corrosion protection in acidic environments have attracted much attention due to their high corrosion inhibition efficiency and low synthesis cost. − Molecular structures of several typical quaternary ammonium salt-based ILs and their anticorrosion performance in acidic environments are summarized in Table . These studies reveal that organic molecules with aromatic rings, especially with nitrogen-containing heterocyclic rings, generally possess high corrosion inhibition efficiency (>90%).…”

A halogen-free quaternary ammonium-based ionic liquid functionalized with benzotriazole, BTA-16-BTA, was synthesized. Its anticorrosion effects on Q235 steel were evaluated in two different acids (6 M HCl or 1 M H 3 PO 4 ) by weight loss and electrochemical tests. BTA-16-BTA shows the best performance at 30 °C with the highest inhibition efficiencies of 98.84% in 6 M HCl and 96.40% in 1 M H 3 PO 4 . The adsorption behavior of BTA-16-BTA molecules on Q235 steel in HCl solution obeys the Langmuir isotherm with an adsorption energy of about −40 kJ• mol −1 , which implies chemisorption. Quantum chemistry calculation indicates that the chemical adsorption originated from the injection of π-electrons from inhibitor molecules into empty 3d orbitals of Fe atoms. The tight adsorption of inhibitor molecules and associated dehydration of the steel surface promoted the corrosion inhibition in HCl solutions. In H 3 PO 4 solutions, passivation by phosphate anions and adsorption of inhibitor molecules contributed synergistically to the excellent anticorrosion performance.

“…Under these conditions, stainless steels are widely used to resist the corrosion caused by CO 2 and/or H 2 S [5][6][7][8] due to the formation of a highly protective layer formed in their surface [9][10][11][12][13][14][15]. One of the most popular cost-effective methods to ght corrosion and its implications in the destruction of metals is the use of corrosion inhibitors, especially organic ones, such as amines, amides, imidazolines and ammonium quaternary salts [16][17][18][19][20][21][22][23][24][25][26].…”

A cationic, Ammonium quaternary surfactant, obtained from avocado essential oil has been used as a corrosion inhibitor for LDX 2101 duplex stainless steel in a CO2-saturated 3.5% NaCl solution. Used techniques involved potentiodynamic polarization curves and electrochemical impedance spectroscopy. Results have shown that ammonium quaternary salt was an efficient mixed type of inhibitor although it affected more strongly the cathodic electrochemical reactions, with a decrease in the corrosion and current density and an increase in the pitting potential values; inhibitor had an efficiency that increased with its concentration from 0 to 25 ppm, but it decreased for higher concentrations. Inhibitor was adsorbed onto the steel surface on a mixed chemical-physical way dominated by a chemical type of adsorption, following a Langmuir type of adsorption isotherm. Corrosion process was charge transfer controlled and it was unaffected by the addition of the inhibitor. Theoretical studies in order to determine the relationship between electronic inhibitor properties and its inhibition efficiency have been carried out by using the DFT methodology.

“…Compounds of various nature are widely studied as corrosion inhibitors (CIs) of steels in this medium [ 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 ]. Of these, quaternary ammonium salts (QASs) [ 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ] often used as components of industrial mixed CIs are important from a practical point of view. Triazole derivatives are a new promising class of acid corrosion inhibitors for steel that possess unique protective properties [ 31 , 32 , 33 , 34 , 35 ].…”

Effect of Quaternary Ammonium Salts and 1,2,4-Triazole Derivatives on Hydrogen Absorption by Mild Steel in Hydrochloric Acid Solution

et al. 2022

The treatment of low-carbon steel items with hydrochloric acid solutions is used in many industrial technologies. This process is accompanied not only by metal corrosion losses, but also by hydrogen absorption by the metal. In this study, the kinetics of hydrogen cathodic reduction on low-carbon steel in 2 M HCl containing corrosion inhibitors, namely, quaternary ammonium salts and a 3-substituted 1,2,4-triazole, have been studied. Adsorption isotherms of corrosion inhibitors on cathodically polarized steel surface have been obtained. XPS data provide valuable information on the composition and structure of protective layers formed on steel in HCl solutions containing inhibitors. The main rate constants of the stages of gaseous hydrogen evolution and incorporation of hydrogen atoms into the metal have been determined. The addition of quaternary ammonium salts or 3-substituted 1,2,4-triazole inhibits the cathodic reduction of hydrogen and its penetration into steel in the HCl solution. 3-substituted 1,2,4-triazole is the most efficient inhibitor of hydrogen absorption. The inhibitory effect of this compound is caused by a decrease in the ratio of the hydrogen concentration in the metal phase to the degree of surface coverage with hydrogen. The maximum decrease in hydrogen concentration in the metal bulk in the presence of the 3-substituted 1,2,4-triazole is 8.2-fold, which determines the preservation of the plastic properties of steel as it corrodes in HCl solutions. The high efficiency of the 3-substituted 1,2,4-triazole as an inhibitor of hydrogen cathodic reduction and absorption results from strong (chemical) adsorption of this compound on the steel surface and the formation of a polymolecular protective layer.
