Abstract: A component, in particular a stator or a rotor, of an electric motor, in which a layer structure is generated is produced, using additive manufacturing, by: forming, via alternate additive production, a layer assembly having first layers and second layers, each first layer including a filament containing plastic and metal, and each second layer including a filament containing plastic and ceramic; heating the layer assembly a first temperature, at which the plastic is removed from the layers; further heating the layer assembly (2) to a second temperature, whereby the metal of the layer is sintered and an electrically insulating ceramic layer is obtained from the layer.

Abstract: A method for producing an impeller of an exhaust gas turbocharger made of TiAl alloy by centrifugal casting, includes providing a TiAl alloy consisting of titanium, 43.7 at-% to 47.5 at-% aluminum, 1.9 at-% to 8.7 at-% niobium, 0.3 at-% to 0.6 at-% carbon, and at most 2.0 at-% others, heating a casting mold used for the centrifugal casting to a casting temperature of 500° C. to 800° C.; introducing the TiAl alloy into the heated casting mold; accelerating the casting mold about a rotation axis spaced apart from the casting mold with an angular acceleration to a rotational speed within an acceleration time period as soon as the TiAl has reached the casting temperature, wherein a rotary axis of the produced impeller is arranged perpendicular to the rotation axis during the centrifugal casting.
