In the case of many machine elements, for example rolling bearings or rolling drives, which are subjected not only to rolling stress but at the same time also to sliding stress, this results in sliding wear in certain zones. In order to reduce this as far as possible, it is proposed to apply to the affected surfaces of such structural units a layer of a sliding bearing material which, however, according to the perception of the invention, has to be applied by a PVD method and has to be of a thickness of the order of magnitude of the surface roughness of the base element; known thicker sliding bearing coatings are not suitable. <??>Application of the invention in particular for gear wheels, rolling bearings, shafts, compressor screws and rolling pistons. <IMAGE> |
