Abstract

Thin titania film consisting of anatase and rutile was deposited on Ti substrates when soaked in a TiOSO₄/H₂O₂ solution and aged in hot water. H₂O₂ corroded the Ti substrates, yielded a porous surface, and kept the solution from peptization. Thicker titania layers were formed in favor of both a greater supersaturation of Ti(IV) in the solution and a higher concentration of hydrated Ti(IV) derived by the corrosion of Ti and the hydrolysis of TiOSO₄. The effects of aging in hot water were accounted for as they caused structural relaxation of the surface layer involving a rearrangement of Ti-OH and eliminating residual species like peroxide ions. Those titania layers were thus favored to deposit apatite when the Ti substrates were placed under a body environment, i.e. soaked in a simulated body fluid of Kokubo's recipe.
