A turbine blade has a blade geometry defined in a coordinate system and at least one cavity which is open to the outside and which has a blade internal surface. At least one planar detection surface, which is accessible for the measuring head of a coordinate measuring device, is formed in the blade internal surface, wherein the at least one planar detection surface is assigned a defined design position and/or a defined design orientation with respect to the coordinate system in which the blade geometry is defined.

A layer system with ceramic layers includes a substrate, a MCrAl(X) layer, which has an oxide layer on the substrate, a lowermost ceramic layer, an outer pyrochlore layer, and a central ceramic layer. The central ceramic layer has a higher porosity at least partially than the outer pyrochlore layer.
