Abstract In this work, the influence of the main spray parameters, such as spray distance, on the microstructure and deposition efficiency of plasma spray-physical vapor deposition (PS-PVD) quasi-columnar structured yttria-stabilized zirconia (YSZ) coating was determined, and the thermal conductivity of the optimum YSZ coating was examined. In addition, the influence of the roughness of the bond coat on the microstructure and thermal shock resistance of the YSZ thermal barrier coatings were also studied, and their failure behaviors were analyzed. The results showed that the coating exhibited good quasi-columnar microstructure with high deposition efficiency when using the parameters of spray power 120 kW, feed rate 20 g/min and spray distance 900 mm. The thermal conductivity of the coating is approximately 0.934 W/(m·K) at 1 100 ℃. Compared with that deposited on the unpolished bond coat, the YSZ columnar crystals on the polished bond coat were well-arranged with less pores and defects and showed better thermal shock resistance performance, which had an average life of 258 cycles and 210 cycles at 1 100 ℃ and 1 150 ℃, respectively.
