Both torches used were a common d.c. current Gas-Stabilized Plasma gun (GSP) with argon and hydrogen as plasma forming gases, and a Water-Stabilized high-throughput Plasma gun (WSP) working with water as plasma forming substance. The feedstock were either cladded alumina/titania powder or a mixture of conventional fused & crushed Al2O3 powder with agglomerated TiO2 nanometric particles, the resulting mean size in both cases being about 50 µm. Feedstock material phases were alumina and anatase titanium dioxide and the composition of both powders was 13 wt% of TiO2 in Al2O3. Coatings obtained were analyzed by scanning electron microscopy (SEM). They presented lamellar structures with titania uniformly distributed in the alumina matrix, for both spray techniques. XRD showed that anatase phase of titania was converted into rutile phase. Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2009
