“…SEM-EDS (JSM-7900F) was applied to examine the change in surface morphology as well as the elemental composition presented on the alloy surface after alloy samples were immersed in NaCl solution in the absence and presence of the inhibitor [ 33 , 34 ]. Furthermore, FT-IR (Nicolet iS50, wave numbers region from 4000 cm −1 to 400 cm −1 ) and XPS (ESCALAB250) techniques were used to study the chemical composition and formation mechanism of the product layer on the surface of these alloy samples [ 35 ].…”

In this work, a cerium/tetraethylenepentamine dithiocarbamate complex was synthesized and evaluated for the corrosion inhibition capability on an AA2024-T3 Al alloy in a 3.5% NaCl medium. The synthesized compounds were characterized via spectroscopic techniques. The corrosion inhibition behaviour of the complex was elucidated by electrochemical measurements and surface analysis techniques. Based on electrochemical test results, the corrosion inhibition efficiency of the complex increases with the immersion time of aluminium alloy in the test solution. The corrosion inhibition reaches 96.80% when the aluminium is immersed in a 3.5% NaCl solution containing a corrosion inhibitor for 120 h. The potentiodynamic polarization test results show that the complex acts as a mixed-type corrosion inhibitor and the passive range is widened. The surface analysis methods reveal that the corrosion inhibition ability of the complex originated from the formation of a protective layer on the Al surface. This film is created from the physisorption and chemisorption of cerium ions and organic parts simultaneously released from the complex molecules.

“…In addition to this, a rise in the polarisation resistance took place and a maximum of 95.8% efficacy to resist corrosion was observed at a particular concentration of 10 –3 M. The potentiodynamic technique suggested it as a mixed type of corrosion inhibitor. Molecular simulations provided additional information regarding the parallel attachment of inhibitors over mild steel surfaces [94].…”

Organic compounds containing heteroatoms have been comprehended to exhibit a remarkable tendency towards corrosion mitigation. This corrosion mitigating tendency is enabled by the presence of electron clouds composed of lone pairs, pi-electrons, which allow them to be adsorbed over metallic equivalents. Because of the availability of nitrogen as heteroatoms, these compounds are being extensively used for corrosion diminution. This article looks at a variety of heterocyclic organic compounds like imidazole, triazole, pyridine, pyrazole, quinoline, tetrazole, pyrimidine, purine and pyrrole, having nitrogen as their prime constituent heteroatom for their anti-corrosive properties. The anti-corrosive properties of these nitrogen-based compounds in acidic conditions have been demonstrated using all available experimental techniques such as EIS, PDP and other theoretical investigations such as DFT and MD. Furthermore, the shift in the trend of these compounds inhibitory efficiencies has been noted and underlined here.

“…The adsorption of inhibitors on steel in the lactic acid solution can be a substitution process of the absorbed water molecules on the metal surface by added inhibitor molecules. Test data obtained from weight loss measurements were used to fit several adsorption isotherm models, and the Langmuir adsorption isotherm was found to be the best fit, which is shown as follows (16) where C inh , θ, and K ads are the inhibitor concentration, the surface coverage of the inhibitor, and the equilibrium constant of the adsorption/desorption process, respectively. The linear relationship between C and C/θ is represented in Figure 5.…”

“…There has been a vast amount of research literature on corrosion inhibitors for mild steel in strong acid media . Organic molecules with structural moieties, such as imidazoles, tetrazoles, triazoles, pyridines, quinolones, Shiff bases, Mannich bases, and quaternary ammonium salts have been investigated to serve industrial demands. Among them, Mannich bases prepared from acetophenone, formaldehyde, and organic amine represent a very important type of corrosion inhibitors used in highly concentrated acid media and at high temperatures. , Unfortunately, conventional commercial inhibitors that work well in the hydrochloric acid system are unsatisfactory when used in lactic acid.…”

Heterocyclic Mannich bases, N -(3-oxo-3-phenylpro-pyl)thiazol-2-aminium chloride (DTZA) and N -(3-oxo-3-phenylpropyl)-1 H -pyrazol-3-aminium chloride (DPZA), were developed for the corrosion inhibition of N80 steel in a 15 wt % lactic acid solution. Weight loss measurements, electrochemical techniques, surface characterization, and theoretical calculations were combined to investigate their anticorrosion performance and mechanism. The results showed that DTZA exhibited a satisfactory inhibitor efficiency of 97.56% with a dosage of 0.15% at 363 K, while DPZA achieved only 58.3% under the same conditions. Adsorptions of both inhibitors on the metal surface followed the Langmuir model with physical and chemical adsorptions. Based on X-ray photoelectronic spectroscopy (XPS) analysis, DFT calculations, and molecular dynamics (MD) simulations, stronger interactions between DTZA and iron than those in the case of DPZA were revealed, leading to the formation of a compact protective film on the metal surface, which is attributed to the presence of a thiazole ring in the DTZA chemical structure.
