摘要

Yttria-stabilized zirconia (YSZ)-based thermal barrier coatings (TBCs) were deposited by supersonic atmospheric plasma spraying (SAPS) and conventional atmospheric plasma spraying (APS). Transmission electron microscopy (TEM) showed that the average height and width of columnar crystals of SAPS-coating were (0.71 ± 0.08) and (0.31 ± 0.04) μm, which was much smaller than that of APS-coating [(2.10 ± 0.10) and (0.48 ± 0.07) μm]. The preferential growth direction of SAPS-columnar crystals was [1 0 1] under rapid solidification. A 3-nm-thick amorphous film was discovered at the splat/splat interface for both APS-/SAPS-coatings.
