文摘

YSZ TBCs was fabricated by supersonic suspension plasma spraying technique. The influence of spray parameters on the deposition rate of SSPS-coatings was presented. Columnar-structured SSPS-TBCs showed the best thermal shock resistance at 1300 °C. The effect of vertical cracks on the thermal stress distribution was discussed.
