| Description | Journal: Iop Conference Series: Materials Science and Engineering Biomedical titanium metals subjected to gas under precisely regulated oxygen partial pressures $(P_{O2}$) from $10^{−18}$ to $10^{5}$ Pa at 973 K for 1 hour were soaked in a simulated body fluid (SBF), whose ion concentrations were nearly equal to those of human blood plasma, at 36.5 °C for up to 7 days. After soaking in SBF, the following relationship held: The growth rate of apatite decreased in the order $P_{O2}$ of $10^{−14}$ Pa > $P_{O2}$ of $10^{4}$ Pa ≥ $P_{O2}$ of 10 Pa > $P_{O2}$ of $10^{5}$ Pa >> $P_{O2}$ of $10^{−18}$ Pa. These results suggest that $TiO_{2}$ containing an optimal level of nitrogen strongly induces apatite formation but samples coated only with titanium nitride do not. Thus, controlling the formation of $TiO_{2}$ and/or titanium nitride is expected to improve the bioactivity and wear resistance of biomedical titanium metal. |
