✦ Synopsis

Three suspensions, containing oxide nanoparticle single phases, (Al 2 O 3 , 3YSZ and Cr 2 O 3 ) were prepared and sprayed using High Velocity Suspension Flame Spraying (HVSFS) technique. The coatings were characterized concerning their mechanical properties by means of nano indenter hardness measurements (all coatings) and ball on disk tribometry (Al 2 O 3 , 3YSZ). APS and HVOF sprayed Al 2 O 3 coatings were characterized under same conditions for comparison. X-ray diffraction analysis was performed on HVSF sprayed Al 2 O 3 and Cr 2 O 3 coatings and a plasma-sprayed Cr 2 O 3 coating for comparison. A Williamson-Hall line profile analysis was performed to estimate and compare crystallite size in the coatings.
