“…As the roughness decrease this indicate that the inhibitor made highly percent of inhibition against corrosion [58]. The lower value of roughness for inhibited solution with comparison to uninhibited one is because the adsorption of the inhibitor on the metal surface which helps for its protection from getting corroded [59].…”

Artichoke extract (AE) was studied as the corrosion inhibitor for zinc in 1 M HCl utilizing chemical and electrochemical methods. The adsorption isotherm of Artichoke extract on Zn surface accords with Langmuir adsorption isotherm. The inhibition efficiency increases with increasing the concentration of the extract and decreases with rise in temperature of the medium. The inhibition efficiency reached a value of 93.2% at 300 ppm of extract. This extract may be forming a film and acts as a barrier, which minimize the contact area between zinc surface and HCl solution. Artichoke extract acts as mixed inhibitor in HCl solution. Thermodynamic parameters of activation and adsorption were determined and explained. The adsorption parameters also obeyed the Langmuir adsorption isotherm and the sign of the free energy of adsorption showed spontaneous process of adsorption. The surface morphology of zinc metal was examined by employing various techniques. Also, the biological effect of the Artichoke extract was studied. Theoretical studies of quantum mechanics and molecular dynamics simulations studies were carried out to the Artichoke extract compounds, and the results agree with the experimental one. The efficiencies marked from all employed techniques were in a perfect correspondence, which demonstrated the validity of these procedures.

“…The CH 2 group of piprazene moiety that was detected at 2.6 ppm (triplet) was verified by the 1 H NMR. The NPPMPQC contains aromatic protons were seen in the range of 7.18 to 8.95 ppm (19) . Singlet signals of the active methylene group, which served as a linker between the phenyl and the tertiary nitrogen of piperazine, at roughly 3.5 ppm and their integration for two protons in each case, are used to demonstrate the formation of NPPMPQC.…”

Objectives: To use the newly synthesized efficient organic corrosion inhibitor N-(4-((4-(pyridin-2-yl) piperazin-1-yl)methyl)phenyl)quinoline-6-carboxamide to carry out on mild steel corrosion inhibition study. Methods: N-(4-((4-(pyridin-2-yl)piperazin-1-yl)methyl)phenyl)quinoline-6-carboxamide was synthesized by stirring method under 0 o C to room temperature at 12 hrs. The synthesized organic inhibitor was characterized by 1 H NMR, 13 C NMR, UV and FTIR spectroscopy. The inhibition effect of organic inhibitor on the mild steel corrosion was investigated with weight loss measurement by gold measuring weighing balance. The inhibitor anchored down on the mild steel surface was analyzed by scanning electron microscopy and Atomic Force Microscopy. Findings: The inhibitor shows a better inhibition efficiency of maximum 74.41% in 1N HCl medium. In addition to this adsorption isothermal models were also interpreted to fit the adsorption behavior of the inhibitor compound on mild steel surface. Thus, the result shows the Langmuir adsorption isotherm. As a result, the interactions between inhibitor and mild steel surface have chemisorptions. Novelty: The N-(4-((4-(pyridin-2-yl) piperazin-1-yl)methyl)phenyl)quinoline-6-carboxamide shows better corrosion inhibition efficiency (74.41%). In addition, inhibitor and mild steel surface show chemisorptions interaction, which confirms free energy and enthalpy of adsorption.

“…This corrosion appears to be more prominent in the fusion zone, which has the highest sensitivity to deterioration and may be accountable for high corrosion potential. The image representation of mild steel after corrosion in an acidic media including defenders represents an adherent inhibitor particles’ layer over the metal’s exterior, which protects it [ 76 , 77 , 78 ].…”

The corrosion inhibition of transition metal chelates derived from Schiff base ligands was tested for (mild, copper, stainless, aluminum and carbon) steel in various concentrations of (HCl, HNO3 and H2SO4) acidic medium at 25 °C through (weight loss, potentiodynamic polarization, polarization curves, electrochemical impedance spectroscopy (EIS) and open circuit potential measurements (OCP)) techniques. The studied compounds were identified with various spectral, analytical and physico-chemical techniques. It was observed that the investigated compounds had a significant inhibitory impact on the corrosion of diverse steels in the medium investigated. The analysis shows that increasing the dose of the studied complexes improves the corresponding inhibitory efficiency values. Negative results of Gibb’s free adsorption energy (ΔGads0) prove the suppression process’s spontaneous and physical adsorption, which contradicts the Langmuir adsorption isotherm. As a result of this insight, a novel bridge between nuclearity driven coordinated inorganic chemistry and materials, as well as corrosion control, has been built. This review provides an overview of the use of Schiff bases and associated transition metals as potential corrosion inhibitors, including the factors that influence their application.
