“…Meanwhile, after oxidation at 700 • C, all the peaks demonstrate TiO 2 phase in rutile form (Figure 2b), indicating that the α + β phases were transformed to TiO 2 phase during oxidation. This is in accordance with the study reported by Aniołek [21], where rutile formed on the Ti surface after oxidation at 700 • C. When oxidation occurs at 900 • C, there is no change in the phase of the oxide scales formed, but some new TiO 2 peaks can be observed (Figure 2c), indicating that the oxide scales contained more TiO 2 phases after oxidation at 900 • C than at 700 • C. Most of the investigations [22,23] have stated that the oxide scales were primarily composed of the TiO 2 phase in rutile form, which is in accordance with the present results. Figure 2 shows that the content of TiO 2 phases increased when the oxidation temperatures increased [24].…”

The Cyclic Oxidation and Hardness Characteristics of Thermally Exposed Titanium Prepared by Inductive Sintering-Assisted Powder Metallurgy

The oxidation and hardness of thermally exposed titanium (Ti) prepared using inductive sintering-assisted powder metallurgy was evaluated through cyclic tests in air at 700-900 • C for 100 h (5 cycles). In general, the oxidation kinetics of the Ti samples followed the parabolic law and their oxidation rates increased with increasing oxidation temperatures. The rutile form of titanium dioxide (TiO 2 ) was detected by X-ray diffraction in the oxide scales after oxidation at 700 • C and 900 • C. Furthermore, the TiO 2 grain size and thickness were significantly influenced by an increase in the oxidation temperature. Lastly, the formation of rutile as a single-phase on the surface of oxidized Ti enhanced the hardness of the oxide scales, whereas the substrate had lower hardness values than the oxide scales due to diffusion of Ti atoms at the surface to form the TiO 2 oxide scales.

“…In this study, the surface roughness yield to the value of 0.13µm, 0.26µm, and 0.31µm for 4, 12, and 36 hours holding times, respectively. According to Aniolek [23], the growth of the oxide layer on the surface was considered as the factor that influences of the surface morphology change. Results of drop contact angles measurements before and after thermal oxidation are presented in The wettability is very crucial parameters for the implants because as a point of the growth of tissues on the surface [26], enhances of wear resistance and improves the corrosion resistance [15].…”

The effects of isothermal oxidation holding time on the surface properties and corrosion behavior in bovine serum of cp-Ti were studied in this paper. The isothermal oxidation was done at 700°C for 0 to 36 hours in air with natural cooling. The surface microhardness, surface roughness, wettability and polarization potentiodynamic corrosion of cp-Ti were determined. The result shows the surface microhardness, surface roughness, wettability and corrosion resistance of the cp-Ti enhanced by isothermal oxidation treatment. The presence of the oxide layer on the surface in the form of TiO2 rutile and Ti3O are responsible to enhance the surface properties and corrosion behavior.

Ti6Al4V titanium alloy is considered a biocompatible material, suitable to be used for manufacturing medical devices, particularly cranioplasty plates. Several methods for processing titanium alloys are reported in the literature, each one presenting both advantages and drawbacks. A decision-making method based upon AHP (analytic hierarchy process) was used in this paper for choosing the most recommended manufacturing process among some alternatives. The result of AHP indicated that single-point incremental forming (SPIF) at room temperature could be considered the best approach when manufacturing medical devices. However, Ti6Al4V titanium alloy is known as a low-plasticity material when subjected to plastic deformation at room temperature, so special measures had to be taken. The experimental results of processing parts from Ti6Al4V titanium alloy by means of SPIF and technological aspects are considered.
