On the corrosion resistance of the submerged arc welded titanium in concentrated hydrochloric acid 8 N

Corrosion behavior of hydrophobic titanium oxide film pre‐treated in hydrogen peroxide solution

“…From Bode plot (Fig. 4a), the capacitive response of the TiO 2 /Ti electrodes only consists one time constant from 10 4 to 10 −2 Hz, resembles the Ti electrode 21, and dislikes the pure capacitor's behavior. Usually, this phenomenon is related to the special preparation method: TiO 2 film prepared by the heating oxidation method 15 has a thick oxide film between the substrate and solution, which causes a time constant in the high frequency region in the Bode plot; but the TiO 2 film pre‐treated by the hydrogen peroxide solution is very thin, there is no retardation while the electron passes from substrate to the TiO 2 film, so possesses a similar Bode plot with Ti electrode.…”

Formation of Vertically Oriented TiO2 Nanotube Arrays using a Fluoride Free HCl Aqueous Electrolyte

“…We believe the narrow processing window is attributed to the complexity of the reaction of Ti in HCl. It was shown by Frayert and co-workers ,, that the reaction of Ti in concentrated HCl includes six rate-determining steps with three possible reaction pathways. Also, hydrogen ions resulting from the dissociation of HCl could be considered to decrease the surface energy and thus increase the film instability .…”

Effect of the solvent on growth of titania nanotubes prepared by anodization of Ti in HCl

“…It is equivalent to the surface tension in liquids. During the reaction between HCl and Ti, Frayret and co-workers [66,67] have shown that the H + and Cl − ions, resulting from the dissociation of HCl, are involved in the determining step of electrochemical dissolution and in the determining step of chemical reaction of depassivation. The ionization equilibrium of an acid (HA) (Eq.…”
