Abstract

In a method for applying a surface structure to a solid body, a structured surface is placed directly or indirectly onto the surface of the solid body and the structure of this structured surface is reproduced in the surface of the solid body, in that an explosive structured layer is arranged on the surface of the solid body and the structure of the explosive structured layer is explosively disseminated into the surface of the solid body. According to the invention, the surface of the solid body is provided with a surface pre-structure before the actual dissemination, at least in regions, wherein the structure of the explosive structured layer is disseminated on at least one partial region of the surface pre-structure so that the surface structure produced results from overlapping of the surface pre-structure with the explosively disseminated structure.
