Sustainable and Green Corrosion Inhibition of Mild Steel: Insights from Electrochemical and Computational Approaches

“…Reliable electrochemical experiments require the establishment of steady-state open circuit condition. Changes in the open circuit potential (OCP) of mild steel over time provide valuable insights into the onset and progression of corrosion. , In this study, the E ocp of mild steel was monitored for 30 min when exposed to the test solutions. Figure illustrates the E ocp of mild steel in the blank solution, showing a shift toward more favorable potentials due to the dissolution of active metals, such as Fe, in the HCl solution.…”

“…Given the abundance of cuminaldehyde and terpene compounds in the oil, the spectrum revealed prominent absorbance bands at specific wavenumbers: an absorbance band at 1607. 1,65 In this study, the E ocp of mild steel was monitored for 30 min when exposed to the test solutions. Figure 2 illustrates the E ocp of mild steel in the blank solution, showing a shift toward more favorable potentials due to the dissolution of active metals, such as Fe, in the HCl solution.…”

“…Steel is widely used in various industries, such as shipbuilding, petroleum, and construction, due to its availability, affordability, and strength. − However, steel is highly susceptible to corrosion in acidic environments, leading to substantial financial losses for industries, estimated to be in billions of dollars annually . Acids are commonly used in industrial processes like petroleum refining, acid pickling, industrial cleaning, acid descaling, and petrochemical operations, exposing metals to corrosive agents. , One frequently used industrial acid is hydrochloric acid, which corrodes metals through chemical or electrochemical reactions. , …”

The Study of 2, 4-Diamino-6-methly-1, 3, 5-triazine on the Corrosion Inhibition of Mild Steel in The Hydrochloric Acid Medium: Integrated Theoretical and Experimental Investigations

“…This means that MS surface is charged with positive with the existence of inhibitor molecules. Mechanism can be described as follows: Negatively charged CIions can be adsorbed on positively charged MS surface at the firs step and the next step may be adsorption of the protonated inhibitor molecules [36]. Inhibitor molecules are protonated in the following way: This electrostatic interaction (physical adsorption) forms a protective inhibitor film on the MS surface and this film prevents the metal from corrosion.…”

Synthesis of mint leaf extract and mint-leaf-based NiO nanoparticles, coating of extract layers without and with NiO nanoparticles on copper through drop-casting, and their analysis for the corrosion prevention in saline water

“…This information suggested that the maximum impedance against the corrosion of Cu was offered by two layers of CEML. 53,54 In the Bode phase plots, the coated Cu showed different curves from the bare Cu and showed different phase angles at the same frequencies, which suggested that the surface of Cu changed due to CEML coating. 55 Thus, the EIS results also confirmed that coating with two layers of CEML was the most effective against corrosion among the studied numbers of layers.…”
