Evaluation of protection performances of Stylosanthes gracilis extract against 304L corrosion in H2SO4 solution

Non-toxic leguminous plant leaf extract as an effective corrosion inhibitor of UNS S30403 in 1 M HCl

“…Organic inhibitors are typically adsorbed on metal surfaces to control the rate of metal corrosion by disrupting either the anodic or cathodic reaction or both. The chemical structure of the inhibitor, the nature of the metal surface, the interaction between organic molecules and the metallic surface, and the type of corrosive medium influence the inhibitor adsorption process [13,16]. The leaf extract of Centrosema pubescens significantly controls the rate of attack of the corrosive electrolyte on the UNS S30403 austenitic stainless steel by disrupting the anodic and cathodic reactions, as shown by the potentiodynamic polarization parameters (Table 3).…”

“…There have been numerous reports on the use of plant extracts as green metal inhibitors in acid solutions [7][8][9][10][11][12]. Watermelon rind, seed, and peel [7], Curcuma longa extract [8], Aloe Vera leaf extract [9], Cucumis sativus peel extract [10], Salvia hispanica [11], Glycyrrhiza glabra leaf extract [12], Stylosanthes gracilis leaf extract [13][14][15] and Centrosema pubescens leaf extract [16] were investigated for their inhibition properties. Nonetheless, more research on other plants that can be used as corrosion inhibitors in industrial applications is required.…”

Preparation and corrosion resistance of superhydrophobic Ni–Co–Al2O3 coating on X100 steel

“…Scholars have long sought to understand how to drastically reduce the harm caused by metal corrosion. Adding corrosion inhibitors, 3 electrochemical protection, 4 coating techniques, 5 and others are the most often utilized protection methods nowadays. However, coating protection is the most cost-effective, common, and practical technique.…”
