A fluid flow machine blade (1) is provided on the outer contour of the airfoil (4) with a thermal barrier coating (41). 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 (42, 43, 44) are realized purposefully without thermal barrier coating. In particular, along the trailing edge (46) of the airfoil, a region (42) is realized without thermal barrier coating. In further embodiments of the invention, regions of the airfoil (43, 44) which lie adjacent to foot-side (21) or tip (31) platforms of the blades are realized without thermal barrier coating.
