“…Much research has been devoted to studying the addition of cerium salts (acetates, nitrates, chlorides) and cerium oxides to the sol to improve corrosion resistance, mainly of aluminium [18][19][20][21][22][23][24][25][26][27]. In this respect, Hinton [28,29] reported a series of rare earth compounds such as cerium nitrate, together with sodium vanadate, sodium molybdate and lanthanum 4-hydroxycinnamate, that improved the corrosion resistance of mild steel and aluminum alloys.…”

One strategy for minimising corrosive attack on carbon steel involves the application of hybrid coatings rich in rare earths, on the basis of their low toxicity and environmental sustainability. Tetraethoxysilane (TEOS) and 3-glycidoxypropyl-trimethoxysilane (GPTMS) were each used here as precursors, together with various quantities of colloidal silica suspension, to improve barrier properties of the coatings. Ce(NO3)(3)center dot 6H(2)O was added as a source of Ce(III) for further inhibition of corrosion. The corrosion resistance of each kind of sample was evaluated using potentiodynamic polarisation measurements and electrochemical impedance spectroscopy (EIS) in 0.35 wt.% NaCI solution. The electrochemical behaviour at various immersion times was modelled by equivalent circuits to demonstrate the effect of silica nanoparticle loading on corrosion. Additional testing was performed under harsh conditions of salt spray chamber. The microstructure and composition of sol-gel coatings were characterised by scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM/EDS), focused-ion beam SEM/EDS analysis, X-ray photoelectron spectroscopy and confocal microscopy.

“…Cerium oxide (ceria, CeO 2 , CeO 2Àx ) nanoparticles are widely studied for their applications in catalysis, 1 chemical and mechanical polishing (CMP), fuel cells, 2 sun-screens, 3 infrared reective pigments, 4 UV 5-7 and corrosion protective [8][9][10] coatings and bio-medicines. [11][12][13][14] The high demand for cerium oxide nanoparticles from the CMP application especially in North America is driving the growth of the global cerium oxide nanoparticle market and the current development technology is not able to cover the increasing demand.…”

“…However, when the cerium salts were incorporated into organic coatings as corrosion inhibitor, the barrier properties of the coating would usually decrease due to leaching process during exposure time. On the other hand, the usage of cerium(IV) oxide nanoparticles directly as inhibitor source was found [18][19][20]. These works demonstrated that the presence of nano-CeO 2 in sol-gel coatings increased the barrier performances and reduced the corrosion rate (about 1000 times compared to uncoated alloy).…”

Abstract. The present work investigated the corrosion protection performance of Ce(III) activated-cerium(IV) oxide nanoparticles for carbon steel in a NaCl solution. Ceria nanoparticles were synthesized by homogeneous precipitation in ethanol/water mixed solvent. The obtained CeO 2 nanoparticles were characterized by X-ray diffraction (XRD) and transmission electron microscope (TEM). The corrosion inhibition action of the activated nanoparticles by cerium(III) ions on carbon steel in NaCl solution was evaluated by electrochemical measurements (electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization). Then, the effect of cerium salt activated-CeO 2 on the protection properties of poly-vinyl-butyral (PVB) coating deposited onto carbon steel plate was studied by salt spray test. The obtained results showed that the salt activated-nanoparticles are anodic corrosion inhibitors. The presence of Ce(III) activated CeO 2 in the coating improved the barrier properties and corrosion protection performance of the PVB coating. No swellings of coating were observed after 48 hours of exposure in salt spray chamber.
