The investigations of (Ti + Al)-SiO2 surfacing by magnetron deposition are presented in this article. The correlation between film`s thickness deposited on the particles by mechanocomposites and magnetron sputtering time was established. It was determined that the rational time for surfacing by Ti-Al mechanocomposites system is about 40 minutes. According that deposition time the thickness of deposited SiO2 films were obtained as 5.2 microns.

“…Temperature was controlled using a chromel-alumel thermocouple placed in the volume of the powder mixture. During the experiment, the inductor was disconnected when the maximum synthesis temperature was reached (Popova et al, 2013;Sobachkin et al, 2019). The inductor and crucible were placed in an evacuated vacuum chamber and then filled with argon.…”

In situ synchrotron studies of structure and phase formation dynamics in mechanically activated (t = 7 min, power density 40 g) and mechanically activated with subsequent irradiation by γ‐quanta 60Co powder mixture (Ti 64 wt% + Al) during high‐temperature synthesis by the method of thermal explosion using induction heating are described. In situ high‐temperature synthesis was carried out on the created experimental complex adapted for synchrotron X‐ray diffraction methods. The sequence of formation and time–temperature interval of the metastable and main phases were determined. The impact of preliminary mechanical activation and of γ‐irradiation on the macrokinetic parameters of the synthesis were studied experimentally in situ. It has been established that the impact of γ‐irradiation on the mechanically activated powder mixture of the composition Ti 64 wt% + Al leads to a change in the thermal parameters of combustion: the maximum synthesis temperature and the burning rate decrease. The heating rate for the non‐irradiated mixture is 204.8 K s−1 and that for the irradiated mixture is 81.6 K s−1. The dependences of mass fractions of the synthesized compounds on time and temperature were calculated from the stage of preheating until completion of the thermal explosion. A single‐phase equilibrium product of the composition γ‐(TiAl) is formed in γ‐irradiated mechanically activated mixture when the system reaches maximum temperature. The synthesized product of the mechanically activated mixture without γ‐irradiation contains 72% γ‐(TiAl); TiAl3 (26%) and residual Ti (2%) are also observed.
