Abstract

TiO₂-Fe₃O₄ coatings on transparent glasses were prepared by atmospheric plasma spraying (APS). As-sprayed TiO₂-Fe₃O₄ coatings consist of anatase TiO₂, rutile TiO₂, Fe₃O₄ and FeTiO₃. The grain size, rate of porosity and fractions of the anatase and TiFeO₃ phases in APS coatings were dependent on the process parameters. With an increase in plasma power, the content of anatase TiO₂ and the rate of porosity in the coatings were decreased while the content of the resultant FeTiO₃ phase and the grain size in the coating were increased. The coating condition of 500 A has the best photocatalytic efficiency and 600 A has the worst. The photocatalytic property of the APS TiO₂-Fe₃O₄ coatings was primarily dependent on synergistic effect of the fractions of FeTiO₃ and anatase phases.
