This work presents a comparative study of five rare earth compounds—Erbium nitrate pentahydrate lll (Er), Neodymium (Nd), Samarium III Nitrate Hexahydrate (Sm), Yterbium Chloride (Yb) and Praseodymium hexahydrate (Pr)—protecting API 5L X70 steel from corrosion in saline medium that uses electrochemical impedance spectroscopy (EIS) polarization curves (CPs) at different concentrations static mode. The results show Erbium is the best inhibitor, containing 50 ppm reaching an inhibition efficiency about 89%, similar result was shown by Sm with IE~87.9%, while other earths (Nd, Yb Pr) showed decrease protection same concentration, since they were below IE~80%. On hand, Langmuir model it possible to describe adsorption process three follows combined physisorption–chemisorption protect metal’s surface. observed free energy, ΔG°ads, reaches −38.7 kJ/mol for Er, −34.4 Nd, −33.6 Pr; whereas have energies −33.9 −35.0 kJ/mol, respectively. Scanning electron microscopy (SEM) atomic force (AFM) further confirmed formation protective film. Their characterization using density functional theory transference charge iron cluster towards metal compounds. produced slightly polarized region interaction Also, found affected magnetic properties surface cluster. Quantum chemical descriptors, such as Pearson’s HSAB (Hard Soft Acids Bases) useful predicting behavior flow electrons between interacting ions.
