Abstract
A composite structure having —at least a first partial surface of a structure and/or of a workpiece and/or of a layer comprising titanium and/or a titanium alloy and/or NiTi, —a polymer which is arranged at least partially or in sections on the first partial surface of the first structure and/or of the workpiece and/or of the layer, —a common anchoring layer, wherein —the polymer is bonded in the contact region to the titanium and/or to the titanium alloy and/or NiTi at least partially or in sections or in the region of the first partial surface, completely or entirely via the common anchoring layer. Furthermore, the invention relates to an electrochemical etching method for producing undercut structures on surfaces of titanium and/or titanium alloys and/or NiTi for mechanical coupling of a polymer to produce a composite structure.
