Interfacial interaction study of EDTA with the defect structure of Fe_3−δO₄ passive film in an aggressive alkaline medium based on the lattice theory of point defects

Abstract

Despite extensive research on the matter of corrosion inhibition efficiency, the interactions between the defect structure of the passive layer and the inhibitor molecules still remain poorly understood.

Autonomous-healing and smart anti-corrosion mechanism of polyurethane embedded with a novel synthesized microcapsule containing sodium dodecyl sulfate as a corrosion inhibitor

“…Published by the Royal Society of Chemistry that the absorbed medium to the coating, which comprises corrosive agents such as Cl À ions, could eventually reach the surface and once again trigger the metal dissolution reactions on the surface. 45 Hence, it is important to have a contingency plan, when the polymerization reaction of linseed oil and a physical barrier layer are not enough for guarantying the corrosion protection. Therefore, presence of the SDS molecules on the metal surface as the second corrosion inhibition mechanism is necessary.…”

Corrosion Behaviors of Tetrasodium Iminodisuccinate (IDS) as an Environmentally Friendly Inhibitor: Experimental and Theoretical Studies

“…And the mechanism of ethylenediamine-tetraacetic acid was investigated. Both the EIS results (83%) and the potentiodynamic test (85%) results indicated that ethylenediamine-tetraacetic acid exhibited the best corrosion protection at 0.05 M [14]. Furthermore, Teymouri et al analyzed four carboxylate derivatives in simulated concrete pore solutions with 0.5 M NaCl for comparative purposes, and the test results showed that Trisodium Citrate (Cit) performed the highest corrosion inhibition at 0.1 M (91%) [15].…”
