摘要：Atmospheric plasma spraying (APS) was used to fabricate 4.5 mol% Y 2 O 3 stabilized ZrO 2 (YSZ) and 4.0 mol% Yb 2 O 3 and 0.5 mol% Y 2 O 3 co -stabilized ZrO 2 (YbYSZ) series coatings with different spraying parameters. This study presents the effects of particle size of feed powder and substrate temperature on the microstructure and performance of thermal barrier coatings. Single -pass and multi -pass experiments were conducted to explore the relationship between the splat and the coatings. The experimental results indicate that adjusting particle size of feed powders and deposition temperature can alter the splat behaviour and microstructure, improve anticorrosion and anti -sintering abilities, and enhance the hardness and elastic modulus. Changes in parameters can cause changes in the microstructure of as -sprayed coatings. Lower substrate temperatures can lead to vertical cracks, finer powders can introduce more microdefects, and conventional sized powders can form larger pores. A coating deposited using a conventional feed powder at a substrate temperature of 800 degrees C shows excellent sintering resistance. A coating deposited using a fine feed powder on 800 degrees C substrate exhibits the best calcium-magnesium-alumina-silicate (CMAS) corrosion resistance.
