Abstract
A fluid flow machine blade () is provided on the outer contour of the airfoil () with a thermal barrier coating (). In this context, quite purposefully, only part-regions of the airfoil have the thermal barrier coating, while well-defined second part-regions of the airfoil () are realized purposefully without thermal barrier coating. In particular, along the trailing edge () of the airfoil, a region () is realized without thermal barrier coating. In further embodiments of the invention, regions of the airfoil () which lie adjacent to foot-side () or tip () platforms of the blades are realized without thermal barrier coating.
