    Abstract: The thermal barrier coating system applied to a substrate for gas turbine blades/vanes/heat shields, comprises a metallic bonding layer having NiCoCrAlX alloy, an inner ceramic layer (10) on the metallic bonding layer, and an outer ceramic layer (13) on the inner ceramic layer. The inner layer has a thickness of 40-50% of the total thickness of the inner and the outer layer. The inner layer has a thickness of 50 mu m. The total thickness amounts of the inner and the outer layer are 600 mu m. An independent claim is included for a metallic component.

    Abstract: The layer system useful in gas turbine blades/vanes/heat shields, comprises a substrate (4) having a pyrochlore structure, an outer ceramic layer (13) on the substrate, an inner ceramic layer (10) present beneath the outer ceramic layer, and a metallic bonding layer (7) present on the substrate and beneath the outer ceramic layer. The inner ceramic layer has a thickness of 10-50% compared to the total layer thickness of the inner- and the outer ceramic layer of 400 mu m.
