摘要	Titania layers were successfully prepared on the surfaces of Ti-6Al-4V alloy via anodic oxidation in H(2)SO(4) or Na(2)SO(4) solutions at room temperature. The titania layers consisted of pure rutile or a mixture of anatase and rutile structures after the Ti-6Al-4V alloy had been anodized in 1.0 M H(2)SO(4) solution at 150 V or 0.5M Na(2)SO(4) solution at 100 or 130 V. Good apatite-forming ability was demonstrated in simulated body fluid. However, surface layers with mainly titanium metallic phase or a pure anatase structure did not possess the ability to induce apatite formation. Anodic oxidation is an effective method to prepare bioactive Ti-6Al-4V alloy that can be used as an artificial bone substitute under load-bearing applications.
