Combining a precipitation-hardening nickel-base alloy with a steel or titanium substrate makes it very easy to repair parts, the nickel-base alloy having good erosion-resistant properties. A method for producing is disclosed. In particular for repairing, a component having a substrate, in particular turbine blades made of steel or titanium, in particular made of martensitic or precipitation-hardening chromium-rich steels, with a localized deposition weld or with an affixed shaped part, in which a precipitation-hardening nickel-based alloy is used as the localized deposition weld or as the shaped part, in which a laser powder deposition weld or an arc deposition weld is performed.

A turbomachine rotor, a rotor blade and a method for assembling a turbomachine rotor are provided. The turbomachine rotor includes a rotor blade with a blade root, a wheel disk with a groove in which the blade root engages such that the rotor blade is maintained in the groove in a positive fit in a radial direction. Further, a pretensioning device is provided, which is supported on the wheel disk as well as on the blade root and which exerts a pretensioning force on the blade root in the radial direction. The pretensioning device is designed such that the pretensioning force can be adjusted when assembling the turbomachine rotor.
