Therefore, in this study, the corrosion inhibitory capacity of neodymium chloride on API X70 steel in a 3.5% NaCl solution at room temperature is evaluated.
The source of [Nd.sup.3+] ions used in this study was neodymium chloride. This salt was obtained by dissolving neodymium oxide in a dilute solution of HCl until a clear solution was obtained.
Because the neodymium chloride molecule is formed by approximately 40% of the [Nd.sup.3+] cation, 30% of the [Cl.sup.-] anion, and 30% of water (at.%), in this study and in order to avoid ambiguities, it was decided to evaluate the effect of the concentration of the rare earth cation as a corrosion inhibitor rather than the salt as a whole.
This is carbothermically treated to produce an oxycarbide that is chlorinated at 400 C (far below the 1000 C required of traditional processing) to create anhydrous neodymium chloride. The mixture is fed to a fused salt electrolysis cell along with iron chloride and boron trichloride to directly dectrowin the alloy powder in a controllable particle size from nanometers to a few micrometers.
