Abstract: Yttria-stabilized zirconia (YSZ) powders containing varying amounts of SiO2 and Al2O3 impurities were plasma sprayed onto metallic substrates and subsequently investigated. The authors were interested in how the impurities affected sintering rates, thermal conductivity, linear contraction, and pore size and architecture among other things. The YSZ coatings were heat treated at 1400°C for 10 hours and then analyzed for the properties mentioned above. A Hot Disk machine was used to measure the thermal conductivity of the coatings.
