Problems solved by technology

This has the disadvantage that the protective layer can be damaged or destroyed in the corrosion-resistant metal sheet or substrate
Another disadvantage is tissue changes in the heat-affected zone

Embodiment Construction

[0031] like figure 1 Illustrated, in an embodiment of the method for producing a plastic-metal hybrid component 1 (the plastic-metal component is figure 2 shown schematically in a free section view), using structural wire 6 unwound from a structural wire coil 5 as a corrosion protection layer made of zinc with a metal surface 3 of a base body 4 made of steel 2 Good bondable additional material. The structural wire 6 is continuously locally shaped from the unwound end 8 of the structural wire 6 into a geometrically determined and / or geometric Interconnected metal elements 9 of indeterminate form. The interconnected elements 9 of the shaped structural wire 6 are applied here successively from the unwound end 8 of the structural wire 6 onto the corrosion protection layer 2 and are welded at the welding point by means of a laser 10 or an alternative focused heat source. 11 places are welded on the anti-corrosion layer 2, such as figure 2 shown. In this case, a surface struc...

Abstract

The present invention relates to a method for producing a plastic-metal hybrid component (1), in which, in order to improve the adhesion of a metal surface (3), provided with a corrosion protection layer (2), of a base body (4) made from metal and at least one plastic component (14), the corrosion protection layer (2) of the metal surface (3) of the base body (4) is provided with a surface structure (13) having undercuts (12). In order to avoid damage to the corrosion protection layer (2) a filler material that binds well with the corrosion protection layer (2) is applied on the corrosion protection layer (2) in a specific and limited manner, in the form of successive, preferably metal elements (9) having geometrically determined and / or geometrically indeterminate shape, via relative movement with respect to same. The elements (9) of the filler material applied to the corrosion protection layer (2) are each melted, for example by means of a laser (10), and welded on the corrosion protection layer (2), producing the surface structure (13), having the undercuts (12), of the corrosion protection layer (2) of the metal surface (3) of the base body (4). In a subsequent direct spraying process, the undercuts (12) of the surface structure (13) are at least partially filled with a thermoplastic plastic component (14) in such a way that the latter engages in the undercuts (12), formingthe plastic-metal hybrid component (1).

Description

technical field [0001] The invention relates to a method for producing a plastic-metal composite component, wherein, in order to improve the adhesion of a metal surface of a base body made of metal provided with a corrosion protection layer to at least one plastic component, the metal surface is protected against corrosion. The corrosion layer is provided with a surface structure with undercuts, which are each at least partially filled with the at least one plastic component in the direct injection process in such a way that the plastic component engages behind the corrosion protection layer. In the undercut of the surface structure, a plastic-metal hybrid component is formed therein. Background technique [0002] Hybrid lightweight components are characterized by a form-locking of a base body, which is usually made of metal, with a plastic part which engages or is attached to said base body. Such lightweight components are used in a corresponding configuration, for example...
