“…Mild steel has been extensively used in several applications including constructions of tanks, petroleum refineries equipment and flow lines as well as transmission pipelines due to its ease of fabrication and low cost [1][2][3][4][5][6]. However, it is vastly exposed to corrosion and deterioration especially in acidic media.…”

The inhibitive action of plant leaf extracts, Crataegus oxyacantha (Hawthorn) and Prunus Avium (Sweet Cherry) on the corrosion of mild steel in 0.5 M HCl solution was investigated using open circuit potential-time measurements (OCP), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. Functional groups of these plants' leaf extracts and their absorption bands were identified by Fourier transform infrared spectroscopy (FTIR) and Ultra-Violet Spectrophotometer (UV), respectively. The leaf extracts showed good inhibition efficiency in hydrochloric acid solution. Potentiodynamic polarization curves revealed that Crataegus oxyacantha and Purnus Avium plants leaves extracts acted as mixed type inhibitors. Theoretical fitting of different isotherms, Langmuir, Florry-Huggins and the kinetic-thermodynamic models was tested to describe the mode of inhibitors' adsorption on mild steel surface. UV spectra proved that the inhibiting action takes place through simple physical adsorption of the extracts molecules on mild steel surface.

Corrosion costs more than a trillion dollars worldwide and with great efforts being made to solve this problem. The toxic effect of components used in the solution of this problem causes new problems with increasing environmental concerns and high costs. Accordingly, green inhibitors have become an alternative protection method with its ecofriendly nature. With the development of green chemistry technologies, the role of plant extracts and biowastes as new corrosion inhibitors in various environments and their protection effect for many materials have been determined. In this study, besides these mentioned topics, test methods, corrosion prevention mechanisms, and economic approaches are summarized.

“…Principally polymers were utilized as covering material rather than inhibitors but due to the exceptionally insoluble nature of the majority of the polymers in aqueous medium, limit their use as a corrosion inhibitor. As of late, a few endeavors have been made to solubilize the polymers for the utilization of corrosion inhibitor (18)(19)(20)(21). Polymers are magnificent consumption inhibitors for metallic antiques in corrosive condition.…”

As corrosion inhibitors for mild steel in acidic media, polymers are emerging materials due to its larger surface coverage area. This paper focuses on the characteristic of water-soluble solvent polyvinyl alcohol (PVA) at interface of mild steel under 0.5 M HCl, examined using electrochemical impedance spectroscopy, Tafel polarization, and weight reduction techniques. The findings of the study revealed that water-soluble polyvinyl alcohol as polymer inhibitor has restraint abilities, up to 93.7 percent for 3 hours in 0.5 M hydrochloric acid. An advanced form of high spatial resolution imaging of surface of mild steel at different stages was found by using scanning electron microscopy which shows that the sample immersed for 3 hrs in 0.5 M HCl with 100 ppm of water soulble PVA inhibitor provides good inhibition quality to corrosion on mild steel surface.
