Abstract
Experiments on deposition of TiO₂ coatings by using the TiO₂ water suspension containing 15 wt.% of the nanosized TiO₂ particles as a spraying material were carried out. The experiments were conducted by the high-velocity air-gas plasma spraying method (unit «Kiev-S»). Thickness of the deposited coatings was 80 +- 12 mm. The anatase/rutile content ratio changed during the spraying process from 79/21 (in powder) to 31/69 (in coating).
