Method for the Regenerative Production of a Turbine Wheel with a Shroud

A turbine wheel includes, a hub body, a plurality of turbine blades integrally formed with the hub body, and a shroud. The shroud encompasses the hub body, is integrally formed with the turbine blades, and interconnects the respective radial outer edges of the turbine blades. A method of producing t...

More Information
Summary:A turbine wheel includes, a hub body, a plurality of turbine blades integrally formed with the hub body, and a shroud. The shroud encompasses the hub body, is integrally formed with the turbine blades, and interconnects the respective radial outer edges of the turbine blades. A method of producing the turbine wheel in one piece via primary forming includes applying a layer of powdered material having a predetermined layer thickness to a construction platform, selectively melting the layer of powdered material with reference to a current layer form of the turbine wheel, moving the construction platform by a predetermined amount, and repeating applying, selective melting, and moving until a last layer of the turbine wheel is formed.
