Abstract: A blade for a continuous flow machine, wherein the blade is formed along a radial direction and has a blade tip and a blade cross-sectional profile with a pressure side and a suction side. The blade has a blade tip surface which is opposite a housing inner wall during operation. The blade tip surface has an abradable coating, wherein the abradable coating is formed in such a way that a wearing away of the abradable coating takes place during operation, when coming into contact with the housing inner wall, wherein the abradable coating is formed with an abradable coating surface, wherein notches are arranged in the abradable coating surface.

Abstract: An arrangement of a plurality of cooling channels within a turbine blade conveys cooling fluid, wherein the cooling channels lead through the turbine blade, which has a blade root, a blade tip, a leading edge, and a trailing edge, to one or more cooling-fluid outlets, wherein the cooling channels are connected to each other at selected locations and extend separately from each other in other regions in such a way that, in the event of damage to the turbine blade in the region of one cooling channel, the cooling by the other cooling channels remains largely unimpaired, wherein at least one cooling channel begins in a region near the leading edge and near the blade root and leads as a diagonal channel through the turbine blade into a region near the trailing edge and near the blade tip.
