abstract = {This paper focuses on the oxidation behavior of novel
double-ceramic-layer thermal barrier coatings (DCL TBCs)
deposited by atmospheric plasma spraying (APS) and
suspension plasma spraying (SPS). Four kinds of APS-SPS DCL
TBCs with dense/porous columnar structured or vertically
cracked microstructures were prepared. The oxidation
behavior of the APS-SPS DCL TBCs were tested and the
underlying mechanisms were further discussed. Results showed
that the developed APS-SPS DCL TBCs have a better oxidation
resistance than the single layer SPS TBC that was tested for
comparison. In the long-term oxidation, the thermally grown
oxide (TGO) can be divided into two layers, the outer mixed
oxide and inner Al2O3 layer, in which the growth rate of
mixed oxide in TGO changed during oxidation. In terms of the
oxidation rate and oxidation lifetime, segmented APS-SPS
TBCs has a slightly better performance than the columnar
APS-SPS TBCs. Among the four different APS-SPS TBCs, the
segmented dense APS-SPS TBCs with low vertical crack density
appears to have more potential to be used for industrial
application.},
