ABSTRACT:
A spinning rotor (1) with a spinning cup (2) has an interior surface coated with a nickel dispersion layer (6) of an essentially even layer thickness having a concentration of hard material grains (7) embedded therein which is clearly less at the surface of the fiber slide face (9) than in the rotor groove. The coating is produced by bathing the spinning cup in a nickel dispersion bath during the final stage of which the concentration of the hard material grains in the bath is reduced at least in the bathing area, while the spinning cup is moved in this bath and rotated around its longitudinal axis while maintaining the spinning cup in a spatial orientation relative to the bath wherein an imaginary plane passing through the rotor groove is at least approximately perpendicular to the surface of the nickel dispersion bath.
