Electrochemical Study of Anodized Titanium in Phosphoric Acid

Electrochemical Study of Anodized Titanium in Phosphoric Acid

The anodization of the Ti-Cu (2%) alloy was carried out in a 5M H3PO4 solution for 2 minutes. The obtained layers are characterized by XPS, X-ray diffraction, and Raman spectroscopy. The results showed that the obtained films are composed of poorly crystallized TiO2 oxide. Electrochemical Impedance...

Also, it is found that the flat-band potential increases with increasing treatment potential.http://dx.doi.org/10.1155/2020/5769071
