| Abstract Scope |
The effect of water vapor on the oxidation behavior of pure titanium at high temperatures is critical. In the present study, the oxidation behavior of pure titanium in dry air and air containing 10 vol. % H2O at 500, 600 and 700 °C for up to 500 h has been investigated. Additionally, the inert Pt marker technique is performed to determine the metal and oxygen transport in the oxide film. A thin Pt film is sputtered on the surface of the pure titanium prior to its oxidation at 700 °C for 100 h. The main focus of this study is to examine differences induced by water vapor such as oxide scale morphology along with the oxygen enrichment in the subsurface zone. Finally, the extent of oxygen-enrichment in the subsurface zone (alpha-case) as a function of temperature and time is determined by the comparison of EPMA and nanoindentation profiles. |
