Titanium dioxide coatings sprayed by a water stabilized plasma gun (WSP) with argon and nitrogen as the powder feeding gas: differences in structural, mechanical and photocatalytic behavior

Original language description

Titanium dioxide coatings were sprayed by a water stabilized plasma gun (WSP) to form robust self-supporting bodies with a photocatalytically active surface. In one case argon was used as a powder-feeding as well as coating-cooling gas whereas in the other case nitrogen was used. Deposits were studied by XRD, HR-TEM, XPS, Raman spectroscopy, UV-VIS spectrophotometry and photocatalytic tests. Majority of the tests was done at the surface as well as at the bottom side representing the contact surface withthe substrate during the spray process. Porosity was studied by image analysis on polished cross sections where also microhardness was measured. Dominant phase present in the sprayed samples was rutile whereas anatase was the main minor component. Hydrogen content in the nitrogen-assisted coating was higher, but the character of the optical absorption edge remained the same for both samples. Photoelectron spectroscopy revealed differences in the character of O 1s peak between both...
