Patent ID: 7491033

Claim:
A fluid flow machine blade comprising: an airfoil having an airfoil leading edge, an airfoil trailing edge, a suction side, and a pressure side, the airfoil, on an outer side of an airfoil contour which, during operation, is flowed around by hot gas on the suction side and on the pressure side, having a thermal barrier coating; wherein only first sections of the airfoil have the thermal barrier coating, and second sections lack a thermal barrier coating; wherein the thermal barrier coating, in the direction of circumfluence running from the airfoil leading edge to the airfoil trailing edge, ends a distance K upstream of the airfoil trailing edge on said suction side and on said pressure side such that an upstream first section of the airfoil has a thermal barrier coating, and a trailing edge region of the airfoil lacks the thermal barrier coating, on both the suction side and on the pressure side; and wherein L is a chord length of the airfoil, and wherein (0.1×L)≦K≦(0.15×L).
