Eco-Friendly Corrosion Inhibition of Aluminum Alloys with Acacia nilotica in Acidic Media
Abstract: Gravimetric analysis was used to examine the corrosion inhibitory effects of Acacia nilotica extract in 0.5 N H2SO4 on aluminum alloy at different concentrations and at 303 K. At a corrosion inhibitor concentration 0.45% at 303 K, the inhibition efficiency is found to be remarkably high (52.25%). Results show that the extract's capacity to inhibit was caused by its adsorption onto the metal surface via the Langmuir adsorption process. For …
