Regime of Superfast Atomic Transport and Related Processes in Titanium Alloy Modified by ion Implantation and Cyclic Thermal Treatment
In this work we study the formation of a relatively thick TiO2 layer on the surface of Ti-6Al-4V alloy after ion-thermal treatment (IThT). A stoichiometric composition closed to the TiO2 layer, its depth, and local oxidation anisotropy were detected by micro-RBS. Anisotropic oxidation observed at so...

| Summary: | In this work we study the formation of a relatively thick TiO2 layer on the surface of Ti-6Al-4V alloy after ion-thermal treatment (IThT). A stoichiometric composition closed to the TiO2 layer, its depth, and local oxidation anisotropy were detected by micro-RBS. Anisotropic oxidation observed at some local areas near the SIMS craters. In this work, a possible mechanism of the oxide layer formation and thermal stability of spherical inclusions size will be discussed in connection with the superfast 18O implant migration and it dissolution at elevated temperatures. It supposed that dielectric spherical inclusions compose from the particles of about few of tenth nanometers in grain size. |
