An electrically conductive contact element for an electrical connector comprises a contact surface having a plurality of caverns arranged under the contact surface in a microstructure and an auxiliary material filled in the plurality of caverns.

Electrical contact element for an electrical connector having microstructured caverns under the contact surface

For improving the current transfer during the electrolytic metallization of workpieces, a method is proposed: (a) providing a metal depositing apparatus, in which the workpiece, at least one anodeand a metal deposition electrolyte AE are arranged and which has a device for electric current generationand at least one current feeding devicewith in each case at least one electrical contact elementfor making electrical contact with the workpiece; (b) bringing the at least one electrical contact elementinto contact with the workpiece; and (c) feeding electric current to the workpiece via the at least one electrical contact elementin order that the deposition metal deposits on the workpiece. Before method step (b), in a further method step (d), deposition metal is deposited on the at least one electrical contact element

Method and apparatus for electrolytically depositing a deposition metal on a workpiece

For improving the current transfer during the electrolytic metallization of workpieces, a method is proposed: (a) providing a metal depositing apparatus, in which the workpiece, at least one anodeand a metal deposition electrolyte AE are arranged and which has a device for electric current generationand at least one current feeding devicewith in each case at least one electrical contact elementfor making electrical contact with the workpiece; (b)

A method is proposed for preparing a structured metallic surface of a body or for the structuring close to the surface or the generation of metallic structures, first of all on a first metal layer or on a first intermetallic layer a second metal layer or a second intermetallic layer, the second layers differing from the first layers, being generated; and thereafter at least the second metal layer or the second intermetallic layer being heated up region by region in such a way that, in that location, there is formed an intermetallic compound using the material of the first intermetallic layer or the first metal layer and the material of the second metal layer or the second intermetallic layer, into which surface regions are embedded, which are at least essentially made of the material of the second metal layer or the second intermetallic layer. In addition to that, a metallic surface of a body is proposed, especially a surface of a plug or an electrical contact element for the electrical contacting or connection of component parts, having such a structure.
