摘要

Production of a uniform defined surface structure on an electrically conducting workpiece comprises depositing a layer matrix made from a metal or metal alloy with embedded particles on the workpiece surface from a galvanic or current-less bath containing particles of defined shape and size made from metal, metal alloy, ceramic, oxides, nitrides, carbides, borides, silicides, sulfates, plastic, diamond, graphite and/or mica. Production of a uniform defined surface structure on an electrically conducting workpiece comprises depositing a layer matrix made from a metal or metal alloy with embedded particles on the workpiece surface from a galvanic or current-less bath containing particles of defined shape and size made from metal, metal alloy, ceramic, oxides, nitrides, carbides, borides, silicides, sulfates, plastic, diamond, graphite and/or mica. The shape of the particles is selected according to the surface topography and the largest diameter of the particles are dimensioned so that it is 1.5-3 times the surface roughness.
