Abstract
In a method for producing a material layer for a rotor of a dynamoelectric rotary machine, a first suspension with binding agent and solid particles is applied through a first screen onto a base to form a first green body, thereby reproducing a first region of a first material with a first degree of strength. A second suspension with binding agent and solid particles is applied through a second screen onto a base to form an annular second green body concentrically to a layer center, thereby reproducing a second region of a second material with a second degree of strength being higher than the first degree of strength. The first and second green bodies are joined such as to form a material recess substantially at a layer center. A permanent material bond of the first and second green bodies and the solid particles is created by heating and/or by compression.
