Abstract
The invention relates to a process for roughening metal surfaces to improve adhesion of layers which are thermally sprayed thereon, in that in a first process step recesses or depressions () are introduced into the surface in a material-detaching or material-removing treatment so that the protruding metal of the surface forms raised microstructures (), in particular projections, ridges, protuberances or bumps, these microstructures being reworked in at least a second process step by shaping and/or breaking so that a significant proportion of the structures form undercuts () in relation to the surface.
