- •
The role of etching and alkali treatment on anodic titanium oxides is analyzed.
- •
At higher anodizing voltages TiO2 pores get larger and more regular, and titanates are formed.
- •
Alkali treatment creates wrinkles and cracks and promotes Na2TiO3 formation.
- •
Titanates promote disorder, increasing radical species formation, enhancing bioactivity.
