ABSTRACT:
The present invention relates to a spinning device, e.g. an open-end spinning rotor (1) with a fiber guiding surface which is provided with a nickel-diamond coating (3) consisting of at least one inner bearing layer (30) and an outer working layer (31). The diamond grains (40) imbedded in the inner bearing layer (30), with a size between 3.5 .mu.m and 5 .mu.m, are larger than the diamond grains (41) imbedded in the outer working layer (31). The inner bearing layer (30) and working layer (31) are interlaced. In manufacture the fiber guiding surface to be provided with a wear-resistant nickel-diamond coating (3) is subjected to at least two coating procedures, whereby in the first coating procedure the bearing surface (30) is produced with larger diamond grains (40) and in the second coating procedure the working layer (31) is provided with diamond grains (41) which are smaller than the diamond grains imbedded in the bearing layer (30).
