摘要：4.5 mol.% Y2O3 stabilized ZrO2 (YSZ) and 4.0 mol.% Yb2O3 and 0.5 mol.% Y2O3 co-stabilized ZrO2 (YbYSZ) series coatings with different spraying parameters were fabricated using atmospheric plasma spraying (APS). This work describes the effects of feed powder particle size and substrate temperature on the microstructure and performance of the barrier coatings. Single pass and multi-pass experiments were conducted to better explore the relationship between splat and coatings. Results show that adjusting feed powders particle size and the deposition temperature can modify the spalts behaviours and the microstructure, improve anti-corrosion and anti-sintering ability, enhance the hardness and elastic modulus. Specially, the coating by conventional feed powder on 800 °C substrate has the excellent sintering resistance, and the coating deposited by fine feed powder on 800 °C substrate has the best CMAS corrosion resistance. ? 2023, The Authors.
