The corrosion inhibition of nanoparticulates zinc ferrite (NZF) pigment was studied. The steel samples were immersed in the NZF pigment extract in 3.5 wt. % NaCl. Electrochemical tests such as electrochemical impedance spectroscopy (EIS) and polarization as well as surface analysis were employed to evaluate the effect of NZF on the steel corrosion. The concentration of Zn and Fe in the pigment extracts before and after immersion of mild steel samples was evaluated by inductively coupled plasma-optical emission spectrometry (ICP-OES). EIS results in total agreement with results of polarization test demonstrated superiority of NZF as an anticorrosion pigment. In the case of samples exposed to NZF extract, the higher resistance and lower double layer capacitance extracted from impedance spectra as well as lower current density from polarization results might be attributed to precipitation of an inhibitive layer on the surface. This was also supported by SEM/EDS and ICP-OES results.

“…10,11 Iron oxide pigments are commonly used in organic coatings to protect ferrous substrates, particularly structural steels, due to their nontoxic, weather-resistant, and mainly opaque properties. [12][13][14][15][16][17][18][19] Magnetite iron oxide pigments (Fe 3 O 4 ) are known as black pigments and used for a wide range of applications. They confer high anticorrosion efficiency in various binders.…”

“…[16][17][18] Moreover, the interactions between the magnetite pigments and carboxyl groups in alkyd (or polyester modified by fatty acid) binders can lead to metal soaps formation which can act as inhibitors at the metal/organic coating interface. 16,19 However, iron oxide pigments agglomerate easily due to their small size and high surface energy.…”

The aim of this study was to evaluate the use of iron-nickel oxide (Fe 2 O 3 .NiO) nanopowder (FeNi) as an anti-corrosion pigment for a different application. The corrosion protection ability and the mechanism involved was determined using aqueous solution of FeNi prepared in a corrosive solution containing 3.5 wt.% NaCl. Anti-corrosion abilities of aqueous solution were determined using electrochemical impedance spectroscopy (EIS) on line pipe steel (API 5L X-80). The protection mechanism involved the adsorption of metallic cations on the steel surface forming a protective film. Analysis of EIS spectra revealed that corrosion inhibition occurred at low concentration, whereas higher concentration of aqueous solution produced induction behavior.
