In recent years, the anti-corrosive properties of natural extracts as environmentally friendly inhibitors have gained considerable interest. This study evaluates potential Marjoram (Origanum majorana L.) essential oil (OML), collected from Salé, Morocco, a corrosion inhibitor for mild steel in 1 M HCl medium. The protection performance OML was assessed using various electrochemical techniques, including potentiodynamic polarization (PDP) and impedance spectroscopy (EIS), well weight loss method. influence concentration temperature on inhibition were investigated. demonstrated pronounced inhibitory benefits via increasing resistance corrosive solution, thus reducing rate to 0.11 mg cm−2 h−1 efficiency 87.1% at an 500 ppm. PDP confirmed that works mixed-type with cathodic supremacy. EIS revealed charge transfer mechanism is main controlling factor process. thermodynamic parameters suggested key role physisorption inhibition, following Langmuir isotherm. Importantly, SEM EDX analyses formation protective layer extract onto surface, which shields surface species. owed functional group-rich phytochemicals OML. Therefore, development bio-based not only step towards more eco-friendly industrial practices, but also meets growing demand sustainable materials world constrained resources.

Exploring Sustainable Corrosion Protection with Green-Synthesized Metal Phosphonates

Published: Jan. 1, 2025

The corrosion inhibition effect of metal phosphonates Co, Ni, and Cu (MePA) based on phosphonoacetic acid (PA) the carbon steel in a 3% NaCl solution were investigated by electrochemical computational methods. Both microwave-assisted low-temperature hydrothermal synthetic methods prove to improve both time energy efficiency. obtained results from potentiodynamic polarization curves impedance spectroscopy (EIS) analysis show that after an hour immersion, efficiency (IE) was 38.98% for CoPA, 40.54% CuPA NiPA, 62.97% PA. IE PA dropped around 40% as immersion increased, indicating development porous, weakly adsorbed coating permits aggressive ions reach surface. Following 21 days NiPA CoPA considerably increase roughly 92.5%, suggesting stable, compact protective layer had formed shifting Tafel slopes indicate inhibitory action is still influenced blocking impacts. These findings suggest especially function mixed-type inhibitors, lowering cathodic anodic processes contribute corrosion. sustains data. relationship between molecular configuration MePA their efficiencies quantum chemical calculations. experimental theoretical research are good agreement.
