“…Hydrochloric acid and sulphuric acid are commonly used for this purpose; however, these acids attack the metal and initiate corrosion. This corrosion can cause serious damage to the metal and degrade its properties, thereby limiting its applications [3][4][5][6][7][8].…”

The adsorption and corrosion inhibition behavior of (E)-2-methyl-N-(thiophen-2-ylmethylidene)aniline (T) at steel/1.0 M HCl interface was investigated using gravimetric and electrochemical methods at 308 K. Inhibition efficiency increased with increase in the concentration of new synthesized Tiophene Schiff base. The potentiodynamic polarization studies revealed that this compound as mixed-type inhibitor. Data, obtained from EIS measurements, were analyzed to model the corrosion inhibition process through appropriate equivalent circuit model; a constant phase element (CPE) has been used. The inhibition was assumed to occur via adsorption of the components of the Thiophene derivative on the mild steel surface which can be approximated by Langmuir adsorption isotherm model. Quantum chemical parameters are calculated using the density functional theory (DFT) method. Correlation between theoretical and experimental results is discussed.

“…The value of was negative, indicating that the compound investigated was strongly adsorbed on the carbon steel surface, and showing the spontaneity of the adsorption process and stability of the adsorbed layer on the carbon steel surface. Generally, values of ∆G° up to -20 kJ mol -1 are consistent with the electrostatic interaction between the charged molecules and the charged metal (physical adsorption), while those more negative than -40 kJ mol -1 involve sharing or transfer of electrons from the inhibitor molecules onto the metal surface to form a coordinate type of bond (chemisorption) [42]. Therefore, it can be assumed that the adsorption of D on mild steel surface occurs, first due to electrostatic interactions, and then to desorption of water molecules, accompanied by chemical interaction between the adsorbate and metal surface [43].…”

“…Despite all these beneficial features, iron is very corrosive, especially in water and air. This corrosion can cause serious damage to the metal, thereby limiting its applications [1][2][3][4][5][6][7]. To prevent iron from acidic aggression, the use of organic inhibitors is one of the most practical methods and cost-effective choices to protect metals against corrosion; most of the well-known acid inhibitors are organic compounds containing nitrogen, sulphur and oxygen atoms [8][9][10][11][12][13][14][15].…”

This work is devoted to examine the effectiveness of pyrazoles 4-(4,5-dihydro-1H-pyrazol-5-yl)-N,N-dimethylaniline (D) on corrosion of mild steel in a 1 M HCl solution, using weight loss measurement at concentration effects. The inhibitor (D) was synthesized in our laboratory. The formation of this pyrazole was carried out with hydrazine and α-unsaturated aldehydes, and the structure was checked by spectroscopic means, such as FT-IR, 1H NMR and 13C NMR. Polarization curves and electrochemical impedance spectroscopy (EIS) methods were used to assess both the corrosion rate and inhibition efficiency. Potentiodynamic polarization showed that D behaved as a mixed-type inhibitor. The Nyquist plots showed that, while D concentrations increased, charge-transfer resistance increased and double-layer capacitance decreased, involving increased inhibition efficiency. Adsorption of the inhibitor molecules corresponds to Langmuir adsorption isotherm. Quantum chemical calculations showed that the inhibitor was prone to be protonated in the acid, and the results were in full agreement with experimental observations.

“…Isotherms investigations demonstrate mechanism on how natural or organic molecules which used as inhibitor adsorb to the MS surface. The adsorption mechanism depends on some significant factors such as nature, electronic properties and charge of the MS surface in addition to solvent adsorption, ionic species, the electronic potential of metalenvironment interface and temperature of environment [46,47]. Interaction of MS with organic molecules is higher than that of MS surface and H 2 O molecules, adsorption will occur.…”

A new benzylidene derivative, namely 3,, has been synthesized and instrumentally confirmed with Elemental Analysis (CHN), Nuclear Magnetic Resonance (NMR), and Fourier Transform Infrared Spectroscopy (FT-IR). Titanium Dioxide (TiO 2 ) nanoparticles (NPs) were synthesized and characterized by X-ray. The mutualistic complementary dependence of BPTA with TiO 2 nanoparticles as anticorrosive inhibitor on mild steel (MS) in 1.0 M hydrochloric acid has been tested at various concentrations and various temperatures. The methodological work was achieved by gravimetric measurement methods complemented with surface analysis. The synthesized inhibitor concentrations were 0.1 mM to 0.5 mM and the temperatures ranging from 303-333 K. The BPTA with TiO 2 -NP as a synergistic inhibitor becomes superior inhibitive effects with more than 96% inhibition competence of MS coupons in a harsh acidic medium. The efficiency of the inhibition improved with increasing BPTA content and also increase with the Synergistic effects of BPTA with TiO 2 -NP. The excellent effectiveness was performed with the 0.5 mM concentration of BPTA and become higher with adding of TiO 2 -NP rising to the maximum inhibition efficiency (IE). However, the inhibition efficacy declined as the temperature rises. Results of BPTA as corrosion inhibitor indicated the obedience of the adsorption of the inhibitor of mixed type on the surface of MS to Langmuir adsorption isotherm. It was found that the BPTA and performance depend on the Synergistic effects, concentrations of the TiO 2 -NP and BPTA, in addition to the solution temperature. Nevertheless, the quantum calculations have confirmed the direct correlation of the electronic characteristics of BPTA with the corrosive inhibitive influence.
