The Role of Corrosion Inhibitors in Protecting Metallic Structures against Corrosion in Harsh Environments

Electrochemical and Computational study of the Ocimum Americanum Extract for steel in Acidic medium: A Green Pathway to reduce the corrosion of steel

“…Synthetic inhibitors, such as phosphates, nitrites, and amine salts, are highly effective and reliable in corrosive conditions. They react with corrosive chemicals, creating a protective coating on metal surfaces [20]. Synthetic inhibitors are ideal for maintenance-intensive applications like offshore platforms, pipelines, and nuclear power facilities, but require careful selection and dosage to avoid environmental harm and system interference [21].…”

“…Acetoxime, a significant chemical raw material, is employed in a multitude of industrial applications. 1–3 (1) Due to its low toxicity and high reducibility, it is commonly employed as a boiler chemical deoxygenation agent, replacing the more toxic hydrazine; 4,5 (2) as a passivator after boiler acid pickling, it effectively prevents secondary corrosion of metals, and avoids the use of toxic passivators such as ammonia and sodium nitrite; 6 (3) as an organic synthesis intermediate, it belongs to a crucial class of organonitrogen compounds used in pharmaceuticals, pesticides, fuels, and organosilane coupling agent synthesis; 7,8 (4) it is also used as an analytical reagent for measuring Ni and Co metal elements. 9,10 Currently, the traditional synthesis of acetoxime mainly involves two steps.…”

Green Corrosion Inhibitors Based on Plant Extracts for Metals and Alloys in Corrosive Environment: A Technological and Scientific Prospection

“…They are a class of substances capable of slowing the corrosion of a metal when added in low concentration to the environment to which it will be exposed. Its mechanism of action is associated with the formation of a protective barrier adsorbed on its surface, which interacts with the reaction sites and decreases the oxidation and/or reduction reactions associated with corrosion [8][9][10], thus, the inhibitors protect metals by slowing down the corrosion processes in one of the following ways: (1) increasing the anodic or cathodic polarization behavior (Tafel curves); (2) reducing the movement or diffusion of ions to the metallic surface and (3) increasing the electrical resistance of the metallic surface [9]. They are commonly classified by their action as cathodic, anodic and mixed inhibitors [10].…”
