Abstract
A process for galvanic depositing of a dispersion layer on a surface of a work piece, in particular a contact layer on a plain bearing half liner, is described, where an electrolyte with the dispersed phase finely distributed therein is moved opposite the work piece surface to be coated with formation of a flow component parallel to the surface. In order to create advantageous processing conditions, the surface of the work piece to be coated is profiled prior to coating with an average minimum profile depth of 5 μm and is then coated transversely to a salient profile direction in a flow component of the electrolyte opposite the work piece surface.
Claims9
A process for the galvanic deposition of a dispersion layer on a surface of a workpiece, which comprises the steps of
- (a) moving an electrolyte with a dispersed phase finely distributed therein over, and relative to, the workpiece surface to coat the workpiece surface, the moving electrolyte with the dispersed phase forming a flow component parallel to the workpiece surface, and
- (b) profiling the workpiece surface with an average minimum profile depth of 5 μm prior to moving the electrolyte with the dispersed phase therover, the flow component running transversely to a salient profile direction.
