초록
The aim of this study was to evaluate the use of iron-nickel oxide (Fe2O3.NiO) nanopowder (FeNi) asan anti-corrosion pigment for a different application. The corrosion protection ability and the mechanisminvolved was determined using aqueous solution of FeNi prepared in a corrosive solution containing 3.5wt.% NaCl. Anti-corrosion abilities of aqueous solution were determined using electrochemical impedancespectroscopy (EIS) on line pipe steel (API 5L X-80). The protection mechanism involved the adsorptionof metallic cations on the steel surface forming a protective film. Analysis of EIS spectra revealed thatcorrosion inhibition occurred at low concentration, whereas higher concentration of aqueous solution producedinduction behavior.
