采用高速悬浮火焰喷涂（HVSFS）技术制备了三种含有单一氧化物纳米颗粒的悬浮液（Al 2 O3、3 YSZ和Cr2 O3）。涂层的机械性能，其特征在于通过纳米压头硬度测量（所有涂层）和球盘摩擦（Al 2 O 3，3 YSZ）。在相同条件下对APS和HVOF喷涂Al 2 O3涂层进行了表征和对比。对超音速火焰喷涂Al 2 O3和Cr2 O3涂层以及等离子喷涂Cr2 O3涂层进行了X射线衍射分析。进行Williamson-Hall线轮廓分析以估计和比较涂层中的微晶尺寸。
Three suspensions, containing oxide nanoparticle single phases, (Al2O3, 3YSZ and Cr2O3) 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 (Al2O3, 3YSZ). APS and HVOF sprayed Al2O3coatings were characterized under same conditions for comparison. X-ray diffraction analysis was performed on HVSF sprayed Al2O3and Cr2O3coatings and a plasma-sprayed Cr2O3coating for comparison. A Williamson–Hall line profile analysis was performed to estimate and compare crystallite size in the coatings.
