摘要：
Titanium dioxide coatings were deposited by utilizing an atmospheric plasma spraying (APS) system, at different spray parameters like argon flow rate and arc current. The structure and crystallite size of the as-sprayed TiO2 coatings were characterized by X-ray diffraction (XRD) and Transmission electron microscopy (TEM). The photocatalytic efficiency was determined in an environmental test chamber and evaluated from the conversion rate of ethanol. The as-sprayed TiO2 coatings were photo-catalytically reactive for the degradation of ethanol and the photo-catalytic activity was influenced by spray conditions. (C) 2011 Elsevier B.V.
