Method for producing an internally cooled turbine blade and gas turbine with a turbine blade produced according to the method

摘要

The method involves forming a cavity (20) that is penetrated through an outer wall contour (10) of the turbine blade (1). The cavity is filled with metal balls (30), so that the metal balls are contacted with each other. The metal balls are non-detachably connected at the contact points (B) by performing the sintering process. The turbine blade is divided into several partial regions that are filled with metal balls of varied diameters. An independent claim is included for gas turbine.
