Anticorrosion Performance of Syzygium Cumini Leaves Extract for Carbon Steel Immersed in a Hydrochloric Acid Medium

IE(%) of SCLAE on CR of CS immersed in 1 N HCl was herein assessed by WL method.The former increased and the latter decreased in the solution with higher Ct of SCLAE.The inhibitor blocked MS corrosion active sites, and created a protective layer that covered its surface.Pc constituents of SCLAE allowed the interaction between their hetero atoms and the metal ions from the CS surface, hindering its corrosion.Elc studies were herein used to confirm the formation of a protective layer on the CS surface.They were further reinforced by surface analysis techniques, such as FTIR and SEM.EDAX was used to analyze the elements present on the CS surface, after its immersion in 1 N HCl without and with SCLAE.Ra of polished, corroded and inhibited CS surfaces was analyzed by SEM and AFM.
