Acacia senegalensis (AS) stems as green corrosion inhibitor for AISI 304 in 1 M hydrochloric (HCl) acid using both gravimetric and potentiodynamic polarization techniques was investigated. The stems were characterized by quantitative and qualitative analyses, Atomic absorption Spectroscopy (AAS), Fourier Transform Infrared Spectroscopy (FT-IR) and Gas Chromatography-Mass Spectrometry (GC-MS). Substrates before and after corrosion were characterized by scanning electron microscopy (SEM). The inhibitor concentration, time and temperature were varied accordingly. Corrosion rate increased with increase in temperature and decreased with increases in both inhibitor concentrations and time. Inhibition efficiency of 98.30% occurred at the value of 8% v/v and phytochemical results revealed tannins, alkaloids, saponins, flavonoids with their contents, AAS revealed 75% calcium, 16% magnesium, 3.35% manganese, FT-IR and GC–MS revealed some elements (N=C=S, C=N), chemical bonds/functional groups (NH2) etc which were responsible for the protection of AISI 304. Inhibition efficiency obtained suggested the effectiveness of the inhibitor. The green inhibitor acted as mixed-type. The coupons without green inhibitor were rough with severe pits, while surface with green inhibitor was protected. The weight loss, polarization and the characterization were in good agreement with each other.

“…Adsorption of an inhibitor is the first step in forming a corrosion protective film or coating in the presence of an aggressive medium that causes corrosion on the active sites. The type of interaction between the inhibitor and the metal surface is best revealed by the Langmuir adsorption isotherm [113]. If the value of ΔG°a ds is -20 kJ•mol −1 or less negative, the type of interaction is known as physisorption, which arises due to the electrostatic interaction between the charged centers of inhibitor molecules and the charged metal surface.…”

Corrosion is a hazardous phenomenon having a devastating impact on technological and industrial applications, particularly in the oil and gas industries. Therefore, controlling the corrosion of metals is an important activity of technical, economical, environmental, and aesthetical importance in order to save huge expenses in materials, equipment, and structure. The use of corrosion inhibitors is one of the best options for controlling the metallic corrosion in various corrosive media. Numerous problems aroused with the use of inorganic and small molecule organic corrosion inhibitors, and the use of polymeric corrosion inhibitors came into limelight. This review article provides an overview of the recent development of different classes of corrosion inhibitors with special emphasis on different functional motifs of natural, synthetically modified natural, and synthetic polymeric materials. The significance, mechanism, and challenges of using polymeric materials as corrosion inhibitors are also highlighted in the review.

“…Several factors affect the adsorption of inhibitor on the metallic surface and isolate it including adsorption mode, chemical and electronic characteristics of the inhibitor, temperature, type of electrolyte employed, steric effects, and the nature and surface charge of metals [63]. The Langmuir adsorption isotherm is the most favorable to clarify interaction between the inhibitor and metal surface [53]. Adsorption on the corroded surfaces approximates to a steady-state adsorption that may be physical adsorption (physisorption) or chemical adsorption (chemisorption), or a mixed adsorption mechanism that is considered ideal for effective corrosion inhibition.…”

Green corrosion inhibitors are of interest because there has been an increase in environmental awareness and a change in regulations that restrict regular corrosion inhibitors due to their toxicity. Natural products are a good source of green corrosion inhibitors, where most of their extracts containing the necessary elements such as O, C, N, and S, which are active in organic compounds, assist in adsorption of these compounds on metals or alloys to form a film that protects the surface and hinders corrosion. Numerous natural products and their application in different processes, especially in steel reinforcement embedded in concrete, are discussed. Development of green chemistry and green chemical technologies offers novel synthetic methods for ionic liquids, which are considered as new corrosion green inhibitors, and their mechanism of adsorption, how these green inhibitors act in different media, and their protective role for different metals and alloys are discussed. Finally, industrial applications of vapor-phase inhibitors and their mechanisms are presented.
