Title: Spinning rotor for an open-end spinning frame

Abstract: A spinning rotor for an open-end spinning frame has a coating of a non-ferrous metal with hard material granules embedded therein, which is applied to the surface of the base material (12), in particular a nickel layer with diamond granules, wherein the coating is comprised of at least two layers (7, 10) containing hard material granules, and an intermediate layer (9) free of hard material granules between the layers (7, 10) containing hard material granules. In case of a separation in places of the wear protection layer, such as can be caused by a scraper in the course of cleaning the spinning rotor, wear protection and spinning properties at the damaged places of the spinning rotor are preserved. As a result, it is possible to prevent a considerable shortening of the service life of the spinning rotor.
