“…e increase in pH of the cathodic sites causes the precipitation of compounds of the type Me(OH) 3 , which subsequently are transformed to more stable metal oxides (Me 2 O 3 ). e mechanism of precipitation of both rare earth oxides and hydroxides has been cited in the literature previously [7,[27][28][29][30]. In general, the hydrolysis reaction of lanthanide cations (Ln) can occur according to the following reactions:…”

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.

“…Their advantage is effectiveness, low toxicity [25,26] and economic competitiveness [27]. Some studies have shown synergy between rare earth salts and organic carboxylate compounds such as salicylate [6,28], cinnamate [29,30], octylthiopropionate [31], dibutyl phosphate [32], hexadecanoate [33], tartrate [34] and mercaptoacetate [35][36][37] in corrosion inhibition.…”

The paper analyses the corrosion behaviour of naturally and artificially aged AA2024 alloy in NaCl solution and in the presence of an environment‐friendly corrosion inhibitor, CeCl3. On the basis of the values of polarisation resistance and corrosion current density, the corrosion resistance of the protective inhibitor film is established as well as the general corrosion resistance of this aluminium alloy. Resistance to pit formation is determined based on the difference in pitting and corrosion potentials while resistance to pit growth is determined based on the amount of charge consumed during pit growth. A scanning electron microscope is used to examine the morphology of the pits formed during the pitting corrosion testing, as well as to determine the cerium content on intermetallic particles and the matrix AA2024 alloy. The corrosion behaviour of AA2024 alloy is investigated after different test periods in NaCl solution and in the same solution with the CeCl3 inhibitor. The corrosion resistance of both tempers of AA2024 alloy is more than one order of magnitude higher in the presence of CeCl3. An explanation of the observed differences in the corrosion behaviour of the naturally and artificially aged AA2024 alloy is proposed. Different corrosion behaviour of the alloy after different test periods is also explained.
