A Study of the Photo-Catalytic Character of Plasma Sprayed TiO_2 Coatings

摘要

Two types of rutile and anatase powders are used for the deposition of TiO_2 coatings. The effects of plasma spraying conditions on the structure of TiO_2 coatings are investigated in order to clarify controlling factors of the phase formation and to aim at the development of effective photo-catalyst TiO_2. It is found that the amount of anatase TiO_2 in the coating is influenced by spray parameters.
