A method for producing a component is disclosed. The method includes calculating a load line of the component as a result of a load to be absorbed by the component and applying a layer on a core by gas dynamic cold spraying, where the layer has a layer section and where the layer section runs along the calculated load line.

Method for producing a component by calculating a load line of the component

The invention relates to a rotor for a turbomachine, in particular a low-pressure turbine rotor for a gas turbine, having at least one stage, each stage comprising a rotor disk having rotor blades attached to the rotor disk, and the rotor disk of each stage being removably connected either to oppositely situated rotor disks of adjoining stages or to a rotor connection of a rotor shaft by at least one respective attachments. According to the invention, the, or each of the, attachment means extends through the rotor disk of at least one stage, whereby the, or each of the, attachment means is guided with radial play into at least one borehole passing through the respective rotor disk, so that an interior borehole surface is not subjected to load or force.
