“…In particular, the best anticorrosive properties have been detected mainly on light alloys, such as alloys based on aluminum, magnesium, and zinc [7][8][9][10][11][12][13][14][15][16][17]. However, some studies on iron-base alloys have also shown that rare earths and their compounds are capable of inhibiting the iron corrosion [4,[18][19][20].…”

In this study, the effect of the addition of Nd 3+ ions as a corrosion inhibitor of the API X70 steel in a medium rich in chlorides was evaluated. e performance of the Nd 3+ ions was evaluated by means of electrochemical techniques such as potentiodynamic polarization curves, open circuit potential measurements, linear polarization resistance, and electrochemical impedance spectroscopy, as well as by means of scanning electron microscopy and EDS measurements. e results showed that Nd 3+ ions reduce the corrosion rate of steel at concentrations as low as 0.001 M Nd 3+ . At higher concentrations, the inhibition efficiency was only slightly affected although the concentration of chloride ions was increased by the addition of the inhibitor. e adsorption of the Nd 3+ ions promotes the formation of a protective layer of oxides/hydroxides on the metal surface, thereby reducing the exchange rate of electrons. Nd 3+ ions act as a mixed inhibitor with a strong predominant cathodic effect.

“…Hinton et al [31][32][33] proved that rare-earths, and particularly cerium, inhibit redox reactions occurring on aluminum alloys. It was highlighted that the improvement of the corrosion resistance is due to the precipitation of cerium compounds on cathodic regions thus promoting the inhibition of reduction reactions [34].…”

t r a c tThis work evaluates the effect of cerium nitrate as corrosion inhibitor for AA2024-T3 in the view of its introduction in sol-gel coatings able to provide self-healing ability. Since it is well established that deposition of Ce species is activated by the local pH increase, the objective of this paper is to investigate the behavior of AA2024-T3 (open circuit potential and polarization curves) in the presence of Ce species in aggressive solutions by means of a local technique, the electrochemical micro-cell. This technique enables the investigation of small areas with resolution in the micrometer range by the use of glass capillaries to define the working electrode area. The micro-cell results clearly displayed that the entire AA2024-T3 area exposed to the ceriumcontaining electrolyte was involved in the cerium precipitation mechanism. The heterogeneous electrochemical behavior of the microstructure is minimized by the formation of a cerium-containing layer able to protect the metal substrate.

“…The reduction of sintering temperature for nanocrystalline cerium oxide overcomes processing temperature difficulty and makes it a promising candidate as an electrolyte in solid oxide fuel cells [52,53]. Ceria can also be used for corrosion protection on a number of different substrates [54][55][56].…”

Rare earth ceramic oxides are used in several applications including, phosphors, gas sensors, fuel cells, catalytic converters, and corrosion protection. These materials exhibit attractive properties such as fracture toughness, stiffness, and high strengthto-weight ratios. Synthesis of rare earth oxides includes a long list of techniques, but electrodeposition is one that has not been used as extensively as other techniques. This chapter discusses in detail the electrochemical synthesis of lanthanum, cerium, and praseodymium oxides. The physical and chemical properties of the electrodeposited oxides are characterized by x-ray diffraction, scanning electron microscopy, x-ray photoelectron spectroscopy, and other techniques. The electrochemical synthesis and post-treatment of other rare earth oxides, such as gadolinium, terbium, samarium, neodymium, europium, and dysprosium oxides are also covered in this chapter. Two main mechanisms of electrodeposition for rare earth oxides are discussed in detail.
