Abstract

Porous titania layers composed of rutile and anatase were formed on the surface of titanium metals by anodic oxidation at voltages of 100, 150 and 180 V in H₂SO₄ solutions, with concentrations of 0.5, 1.0 and 2.0 M. Pore size increased with increasing applied voltage from 100 to 180V under a constant H₂SO₄ concentration of 0.5, 1.0 or 2.0M. The relative amount of rutile to anatase and the apatite-forming ability of titanium metals increased with increasing applied voltage from 100 to 180 V under a constant H₂SO₄ concentration of 0.5, 1.0 or 2.0 M and increasing H₂SO₄ concentration from 0.5 to 2.0 . Munder a constant applied voltage of 100, 150 or 180 V. Titanium metal anodically oxidized at 180 V in 2.0M-H₂SO₄ solutions showed extremely high apatite-forming ability in simulated body fluid (SBF).
