Embodiment Construction

[0023] exist figure 1 The structural part assembly according to the invention is identified in its entirety by the reference numeral 10 . The structural component assembly 10 is designed here as a running device (rotor) 10 . The running device 10 has a structural part 12 configured as a running wheel. The operating device 10 also has a shaft 14 configured as a steel shaft 14 .

[0024] The running wheel 12 has a base body 16 which is connected to the steel shaft 14 via a connecting region 18 . The connection of the running wheel 12 to the steel shaft 14 is produced here by means of a fusion welding method. The running wheel 12 or the base body 16 has a first alloy in the connecting region 18 . The base body 16 of the running wheel 12 can also consist entirely of the first alloy. The first alloy can preferably be a titanium-aluminum-based alloy.

[0025] Now in order to be able to connect such a running wheel 16 , especially marked by its low density and high specific str...

Abstract

A method for producing a component, in particular a rotor wheel, includes positioning a main body, a fusion-weldable attachment layer, and a barrier layer. The main body has a first alloy in an attachment region. The fusion-weldable attachment layer is positioned in the attachment region of the main body and has a second alloy which differs from the first alloy. The barrier layer is positioned between the main body and the fusion-weldable attachment layer. The barrier layer is configured to prevent a reaction of the first alloy of the main body with the second alloy of the fusion-weldable attachment layer during a thermal treatment. The method further includes heating the main body, the barrier layer, and the fusion-weldable attachment layer to connect the main body, the barrier layer, and the fusion-weldable attachment layer to one another.

Description

technical field [0001] The invention relates to a method for manufacturing a structural part, especially a running wheel, and to a structural part, especially a running wheel, and a method for manufacturing a structural part assembly, especially a running device, and to a structural part assembly Especially running devices. Background technique [0002] Exhaust gas turbochargers are increasingly used in contemporary internal combustion engines in order to realize more economical but more dynamic and comfortable diesel and gasoline engines. Nickel (Ni)-based alloys are currently used as materials for exhaust-side turbines. To improve dynamic properties more and more titanium-aluminum (TiAl) based alloys are in focus, which are characterized by low densities (~4 g / cm 3 ) and high specific strength. Turbines produced from titanium-aluminum-based alloys can be produced, for example, by investment casting methods or metal injection molding (MIM). A bigger challenge was connec...
