摘要：

The suspension plasma spray (SPS) technique has recently attracted attention due to the variety of microstructures achievable using submicron spray particles mixed with a solvent to form a suspension. Thermal barrier coatings (TBCs) with a columnar microstructure can be obtained using SPS. Because of its unique columnar microstructure achieving high strain tolerance, a top coat sprayed using this technique can efficiently suppress thermal cycling damage in SPS-TBCs. However, there are few reports on the effect of microstructure on the damage behavior of SPS-TBCs with a columnar structure. In this study, the effect of the top coat microstructure on the thermal cycling fatigue of SPS-TBCs was investigated. The size of the complex oxide formed on the top coat-bond coat interface and the length of the cracks at the interface (formed as a result of thermal cycling) increase with the column diameter in the top coat of SPS-TBCs. The thermal spray conditions affect the thermal cycling fatigue life of SPS-TBCs. The SPS-TBC with fine columnar structure exhibits superior thermal cycling fatigue life.
