Investigation of the corrosion inhibition performance of snail slime on the exposed surface of mild steel in acidic environment

Enhancing aluminum foil performance in aqueous and organic electrolytes: dual-secure passivation with phthalocyanine as a corrosion inhibitor

“…The corrosion current density ( I corr ) and corrosion rate are often inversely related. 43–45 This indicates that the corrosion current value is more significant in estimating the actual corrosion rate of a material; 46,47 the calculated results are also shown in Table S2 †. The corrosion potential ( E corr ) increases with the addition of the Pc corrosion inhibitor.…”

Unraveling the corrosion inhibition behavior of prinivil drug on mild steel in 1M HCl corrosive solution: insights from density functional theory, molecular dynamics, and experimental approaches

“…The mild steel sample utilized for corrosion studies was characterized by a composition with a purity percentage of Mn-1.27, C-0.08, Si-0.01, P-0.02, and Fe-98.62%. The dimensions of the mild steel specimen employed for weight loss corrosion measurements were specified as 1 cm 2 , providing a standardized size for testing purposes (Chukwunyere and Egbosiuba, 2023; Frontiers in Chemistry frontiersin.org Mubarak et al, 2023). Before conducting corrosion tests, the sample underwent thorough preparation to ensure consistency and reliability of results.…”

“…2.6 Surface morphology analysis 2.6.1 Scanning electron microscopy (SEM) SEM is a potent imaging method utilized to evaluate, at extreme magnification, the surface shape and characteristics of materials. SEM was used in this work to evaluate the mild steel specimens' surface features and morphological alterations (Swathi et al, 2023a;Chukwunyere and Egbosiuba, 2023). Once the samples were exposed to the corrosive atmosphere for 6 hours, both with and without Prinivil, they were meticulously prepped and positioned on SEM stubs.…”

“…In acidic environments, such as a 1 M HCl solution, mild steel is susceptible to corrosion. The corrosive attack occurs through the dissolution of iron ions from the metallic surface, culminating in the degradation of the steel ( Chukwunyere and Egbosiuba, 2023 ). However, the existence of an effective corrosion inhibitor like Prinivil can mitigate this process by forming a defensive layer upon the substrate, thus preventing corrosive entities from accessing the metallic surface.…”
