Method for producing a plastic-metal hybrid component

A method for production of a plastic-metal hybrid component in which, in order to improve the adhesion of a metal surface of a main body formed from metal provided with an anticorrosive layer and at least one plastic component, the anticorrosive layer of the metal surface of the main body is provided with a surface texture having undercuts, which are respectively at least partially filled with the at least one plastic component during a direct injection process in a manner such that the latter interengages behind the undercuts of the surface texture of the anticorrosive layer of the metal surface of the main body, whereupon the plastic-metal hybrid component is formed, wherein an additional substance which can readily be joined to and which is electrochemically compatible with the anticorrosive layer of the metal surface of the main body formed from metal is applied, in a specific and limited manner, in the form of successive elements with at least one of:

• a geometrically determined shape, or geometrically indeterminate shape, to the anticorrosive layer of the metal surface of the main body by movement relative thereto, and the respective elements of the additional substance applied to the anticorrosive layer are melted and welded to the anticorrosive layer,
• wherein a texturing wire which is unrolled from a wire coil is used as the additional substance which can readily be joined to the anticorrosive layer formed from zinc of the metal surface of the main body formed from steel,
• which is consecutively formed, in sections from the unrolled end of the texturing wire, into interconnected metallic elements with at least one of:
• a geometrically determined form or a geometrically indeterminate form, by means of a wire forming machine tool which is positioned above the anticorrosive layer and moved relative thereto, the respective elements being consecutively applied to the anticorrosive layer from the unrolled end of the texturing wire and welded to the anticorrosive layer by means of a laser or an alternative focused source of heat.
