Abstract
The failure of thermal barrier coatings (TBCs) fabricated by atmospheric plasma spraying (APS) during thermal cycling is often attributed to the accumulation of the thermal stress. However, in the end it comes down to the growth of thermally grown oxide (TGO) and propagation of the cracks around the TGO. Based on the 8 wt.% yttria stabilized zirconia (YSZ) TBCs fabricated by APS (APS-TBCs), the geometrical shape of the TGO layer which is located...
