“…According to the research conducted by NACE International corrosion poses a significant economic challenge, due to an average annual cost of $2.45 trillion, which is 3.4% of the world's gross domestic product [2]. The use of mild steel for industrial purposes has been increased due to its mechanical properties, malleability, toughness, availability and its low cost [3]. During industrial processes like etching, acid pickling, acid descaling, acid cleaning, and oil-well acidification, mild steel comes in contact with acidic solutions.…”

The inhibition efficiency of the synthesized inhibitor 3-[(4-methoxy phenyl)imino]-1,3-dihydro-2H- indole-2-one in 0.1 N HCl solution was studied by using weight loss, electrochemical analysis like open circuit potential and potentiodynamic polarization methods. It was observed that the inhibition efficiency increases by increasing the concentration of the inhibitor. Maximum inhibition of 92.10% was observed at 600 ppm inhibitor concentration. The inhibitor works as an efficient anti-corrosive agent and it was also supported by electrochemical data. From the results obtained, it was observed that the data best fitted Langmuir adsorption isotherm. The polarization studies indicated that the used inhibitor is a mixed type of inhibitor. The thermodynamic parameters of activation energy and adsorption suggested that the used inhibitor supported both physical and chemical adsorption processes. The protective layer formed on the mild steel surface was analyzed by using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDAX) techniques. The results obtained from weight loss analysis, electrochemical analysis and surface analytical techniques were in good agreement with each other.

The corrosion inhibition efficiency of Plumeria rubra flower extract (PRFE) on 5LX70 mild steel in 4% NaCl aqueous medium was studied by electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and density functional theory (DFT). The PRFE was analyzed by FTIR for the confirmation of functional groups in the extract molecules. EIS and PDP methods indicated that the corrosion inhibition was increased with an increase in the concentration of inhibitor, with a surface area coverage of 90.12%. Polarization results revealed that PRFE is a mixed‐type inhibitor. A maximum corrosion inhibition of 90.98% was achieved at 120 ppm of extract concentration. Quantum chemical parameters of the inhibitor molecules were calculated using the DFT method to ascertain the relation between the parameters and inhibition efficiency. Molecular descriptors like HOMO, LUMO, energy gap, absolute electronegativity, electrostatic surface potential, and so on, were determined, and found that the inhibitor molecules favorably formed a protective layer on the metal surface. The Mulliken charge analysis of the constituent atoms of selected PRFE molecules further supported in identifying the active sites for binding with the mild steel surface. Experimental results have confirmed that PRFE is a good corrosion inhibitor for mild steel which was further affirmed by the computational study.
