“…Electrochemical studies were performed using Biologic SP300 through a conventional three-electrode cell system consisting of mild steel as a working electrode, platinum wire as counter electrode and Ag/AgCl as a reference electrode 20 . The working electrode was immersed in 1N HCl at different concentrations of TBAB.…”

The corrosion inhibition behavior of Tetra-n-butylammonium bromide (TBAB) on mild steel (MS) in 1N HCl was investigated through experimental and theoretical studies. Inhibition efficiency is found to have increased by a rise in the concentration of TBAB. Experimental (weight loss study, potentiodynamic polarization, electrochemical impedance spectroscopy) results suggested that TBAB exhibits better inhibition efficiency. Thermodynamic studies were discussed. TBAB on the mild steel surface obey Langmuir adsorption isotherm. SEM and AFM studies confirm the adsorption and protective ability of TBAB on mild steel in 1N HCl medium. Formation of a protective layer on mild steel was characterized by FT-IR, UV-Visible and XRD studies. Furthermore, quantum chemical parameters were calculated. The results demonstrate the adsorption capability of TBAB on mild steel in 1N HCl medium. Quantum chemical calculations are in good agreement with results obtained from experimental methods.

“…nitro, hydroxy, amine, etc.) or possess plentiful of π-electrons, therefore these compounds will be provide a large protection for metals through their adsorption on the metallic surface, thereby they excellent to inhibit of corrosion (Khadom, 2017;Bouakkaz et al, 2017;Subramanyam et al,1993;Galai et al, 2017;Adbul Nasser et al, 2012). Organic inhibitors can adsorb onto the metal surface by four distinct mechanisms (i) electrostatic attraction between charged molecules and metal, (ii) interaction between electron pairs of molecule and the metal, (iii) interaction between π-electrons of molecule and metal, and (iv) a combination of mechanisms such as (i) and (iii) (Shorky et al, 1998).…”

To inhibit corrosion of the AISI 4130 steel in 1M H 2 SO 4 solution at different temperatures, the gemini surfactant was used, namely N,N'-((1,4-phenylenebis(azanediyl)) bis (2-hydroxy propane-3,1-diyl)) bis (N,Ndimethyldecan-1-aminium) (PAPM). The gemini surfactant by electrochemical impedance spectroscopy technique and weight loss method has been evaluated at different temperatures 30, 40 and 50°C. The gemini surfactant showed a very good performance as a corrosion inhibitor in acidic solution, and inhibition efficiency increases with increase inhibitor concentration but decreased with increasing temperatures. Impedance technique results shown, that studied molecule act as mixed-type inhibitor toward AISI steel, also values of standard free energy of adsorption suggest the physisorption and chemisorption were occurred for inhibitor molecules on AISI surface. In addition, the inhibitor adsorption behavior on the AISI surface was investigated at specified temperatures and it coincide with Langmuir's adsorption isotherm. Furthermore, time effect on corrosion inhibition efficiency was studied where results shown that influence was slight. From quantum calculations, the inhibitor act as soft molecule were noted, also it was shown that the inhibitor more responding for reacting with the AISI surface and prefer the electrophilic attack because it contains on a nucleophilic centers. Experimental inhibition efficiency obtained from both two methods are on a good agreement to each other where optimum efficiency reached 90.32% for weight loss method and 87.17% for EIS technique. On other hand, theoretical inhibition efficiency and experimental inhibition efficiency were in a good agreement to each other, where as theoretical efficiency reached 92.35%.
