Abstract

"Alpha solid solutions of oxygen in titanium dissolving in hydrofluoric acid exhibited a positive difference effect with k values of 5.7, being independent of the concentration of HF, within the compositional range studied 0 to 5 w/o oxygen. This indicates that various TiOx alloys are polarizable to the same extent by the same strength of anodic current in hydrofluoric acid.

The difference effect observed on TiOx alloys dissolving in HF-HCl revealed that the effect is dependent on the oxygen content of the solid solution as well as on the concentration of HCl. The presence of HCl results in a higher k value for the difference effect and accordingly a higher polarizability of TiOx. Measurements of dissolution potentials under different anodic current densities indicated the presence of a protective layer on the surface of the dissolving alloy. These measurements also give support to the explanation of higher polarizability in HF-HCl than in HF alone by the formation of protective layers, and by the effect of HCl on the nature of this layer"--Abstract, page ii.
