Synergistic corrosion inhibition of low carbon steel in HCl and H₂SO₄ media by 5-methyl-3-phenylisoxazole-4-carboxylic acid and iodide ions

Shell of Viviparid Snail as an Eco-Friendly Corrosion Inhibitor for Carbon Steel in 1 M HCl

“…The maximum displacement of corrosion potential for CS under four temperature conditions were 47 mV, 23 mV, 56 mV and 46 mV (all less than 85 mV), which further indicates that SVSE is a hybrid corrosion inhibitor. The corrosion inhibition efficiency can be calculated by Equation (10) [55]: i 0 corr and i corr represent the corrosion current density before and after the addition of corrosion inhibitor, respectively. The maximum corrosion inhibition efficiency η p % after SVSE addition at all four temperature conditions is above 92%, and the results are closer to those calculated by EIS.…”

Synergistic Effect of Benincasa hispida Peel Extract and KI on the Corrosion Inhibition of Mild Steel in HCl

“…In recent times, plant extracts have gained attention as environmentally friendly and cost-effective corrosion inhibitors due to the numerous compounds present in them, such as alkaloids, amino acids, organic acids, monosaccharides, polysaccharides, and proteins, containing a significant amount of hydroxyl and unsaturated functional groups, which could inhibit metal corrosion [15][16][17][18][19][20]. However, the corrosion inhibition efficiency of a single plant extract may not be optimal, and combining it with other substances could increase its effectiveness [21][22][23][24].…”
