Abstract (en)
[origin: EP0970779A2] The surface (4) has particles of a deep fine structure from radiation in several stages. The surface is first given a deep coarse structure to form an embossing surface. The surface is next given a deep fine structure in a first radiation stage, with an initial surface roughness. A protective layer is coated over the surface in the area of the troughs (6) of the coarse structure. The peaks (8) protruding from the protective layer are provided with a fine structure with a second surface roughness, by radiating with particles (12) in a second radiation stage or by etching or other method.
