Abstract	Thick (1.8 mm) thermal barrier coatings were air-plasma-sprayed onto two different substrate geometries, including small circular substrates and burner cans. Two different top-coating spray parameters were used, where the settings of the substrate temperature and the lamella thickness were varied. A segmentation crack network was found in the top coatings sprayed using a high substrate temperature and a high lamella thickness. The density of segmentation cracks was found to be independent of substrate geometry. No segmentation cracks were found in the top-coatings when a low substrate temperature and a low lamella thickness were used.In the segmented burner can, after 1000 thermal shock cycles, the segmentation crack network was still stable and no severe cracks had formed in the top coating. In the nonsegmented burner can, cracks were formed after only 35 thermal shock cycles. Among the crack types, horizontally oriented cracks were found in the top coating close to, and sometimes reaching, the bond coating. Cracks of this type are not tolerated in thermal barrier coatings because they can cause failure of the coating.Regarding the lifetime of the segmented burner can, it is believed the failure will be dependent on other mechanisms, such as bond-coating oxidation or top-coating decomposition.
