Název v původním jazyce

Atmospheric plasma sprayed (APS) coatings of Al2O3?TiO2 system for photocatalytic application

Popis výsledku v původním jazyce

The goal of this study is to examine the photocatalytic ability of coatings produced by atmospheric plasma spraying (APS). The plasma gun used is a common gas-stabilized plasma gun (GSP) working with a d.c. current and a mixture of argon and hydrogen asplasma-forming gas. The TiO2 powders are particles of about 100 nm which were agglomerated to a mean size of about 55 mm, suitable for spraying. Composition of the commercial powder is 13 wt% of TiO2 in Al2O3, whereas also in-house prepared powder with the same nominal composition but with agglomerated TiO2 and conventional fused and crushed Al2O3 was sprayed. The feedstock materials used for this purpose are alpha-alumina and anatase titanium dioxide. The coatings are analyzed by scanning electron microscopy (SEM), energy dispersion probe (EDS) and X-ray diffraction. Photocatalytic degradation of acetone is quantified for various coatings. All plasma sprayed coatings show a lamellar structure on cross section, as typical.
