An experimental study on the growth of Titanium dioxide nanotubes (TNTs) during the three-electrode anodization technique of Ti substrate in fluoride-ion /ethylene glycol (EG) electrolyte has been conducted at 20 V for 30 minutes.The evolution of this nanostructure includes the inward growth of a compact porous layer at the oxide/Ti substrate interface that grows into nanotubes.A further explicati...
