NiCoCrAlYTa splats and coatings were deposited on K4169 substrates by low pressure plasma spray (LPPS) and atmospheric plasma spray (APS), respectively. The microstructures of the splats, and some fundamental properties of the coatings were evaluated in detail. The results show that the splats collected by LPPS performed as disk-shaped ones, while the coating was quite dense with low oxygen content. On the contrary, the splats caught by APS mainly deposited as splash shapes, while the coating has high porosity and oxygen content. 7YSZ splats were deposited on the mirror polished K4169 substrate and low pressure plasma sprayed NiCoCrAlYTa coating respectively, the microstructures of 7YSZ splats were also observed. Typical disk-shaped 7YSZ splat with network of fine cracks and macro circle crack could be found on the K4169 substrate; while the 7YSZ splat deposited on the NiCoCrAlYTa coating has some splash fingers surround the central solidification core, the macro circle cracks almost disappear and less network fine crack could be found, because the intermetallic bond coating can fill the thermal expansion mismatch between substrate and ceramic splat.
