Abstract:
1. A method for applying, at least in regions, a surface structure to a solid body, wherein a structured surface is placed onto a surface of the solid body and the structure of this structured surface is reproduced in the surface of the solid body, the method comprising the steps of: a) providing the surface of the solid body with a surface pre-structure; b) disposing, following step a), an explosive structured layer on the surface of the solid body; and c) disseminating the structured surface into the surface of the solid body through explosive ignition of the explosive structured layer, wherein structure of the explosive structured layer is disseminated on at least one partial region of the surface pre-structure to produce a falsification protected surface structure from at least regional overlapping of the surface pre-structure with explosively disseminated structure.
