Abstract
  • Anodic oxidation method is used to produce thick titanium oxide (TiO2) coating layer in a mixture of acids electrolyte to modify the TiO2, which is naturally formed on titanium with only a few nanometres thick and inert. TiO2 coating is then subjected to an in-vitro test to evaluate their bioactivity in simulation body fluid (SBF) under Ultraviolet irradiation (UV) irradiation. Surface morphology is used to characterize the bone-like apatite, absorption analysis is used to characterize the oxide surface chemical functional bonds and contact angle is used to characterize the surface wettability. The results demonstrate that UV has promoted faster apatite precipitation and full apatite precipitation with time, due to increased Ti-O- and Ti-OH functional groups on the TiO2 coating and strong Ti-OH have obtained higher apatite precipitation in dark and with UV.
