- Sheet metal with an adhesion promoter coating as a semi-finished product for the production of metal-thermoplastic composite components and a method for producing such a sheet
- the present invention relates to a metal-containing, preferably a steel-containing or steel-containing sheet with an adhesion promoter coating as a semi-finished product for the production of steel-thermoplastic composite components, a method for its production and the use of a sheet with an adhesion promoter coating as a semi-finished product for the production of metal-thermoplastic composite components.
- composite materials made of metal preferably steel and thermoplastics, are used, such.
- metal components preferably steel and thermoplastics
- plastic in which plastic is injected.
- thermoplastics made of metal and thermoplastics can only be produced in a materially bonded manner with the aid of adhesion promoters or adhesion-promoting surface treatments, since the thermoplastic itself is not chemically reactive.
- the composite is particularly at risk at the interface between the sheet metal and the plastic, since two different materials are joined here, which can result in increased thermal stresses due to different thermal expansion coefficients between the joining partners.
- the diffusion of moisture, other media, salts, etc. into this interface can have a detrimental effect on the strength of the material composite. This aging in the joining area is referred to as corrosive degradation and can ultimately lead to the destruction of the bond.
- thermoplastic In addition to an activation or chemical modification of the thermoplastic, it is also known and customary, in the production of metal-thermoplastic composite components, to apply the adhesion promoter directly to a metal sheet, e.g. B. on a galvanized sheet steel to apply.
- a metal sheet e.g. B. on a galvanized sheet steel
- the corrosion resistance of the sheet with the adhesion promoter applied to it is not optimal, especially in areas with a damaged adhesion promoter layer. If the adhesion promoter layer is damaged, infiltration corrosion can intensify in the affected areas. Examples of damage are cracks, Cut edges, punchings as well as scratches and holes in the coating. This also applies to damage in the hybrid component that is designed in such a way that the sheet metal / thermoplastic interface with the adhesion promoter is accessible to diffusing salts and moisture.
- the object of the present invention is to provide an alternative sheet metal with an adhesion promoter coating and a method for its production which overcomes the aforementioned disadvantages known from the prior art and is characterized in particular by good adhesion and high corrosion resistance of the sheet with an applied adhesion promoter coating.
- the invention solves this problem with the features of the claims and in particular by providing a sheet with an adhesion promoter coating as a semi-finished product for the production of metal-thermoplastic composite components, comprising a metal-containing sheet and an adhesion promoter coating, with a titanium-containing and / or zirconium-containing conversion layer between the metal-containing sheet and the adhesion promoter coating is arranged.
- the metal-containing sheet is preferably a steel-containing or steel sheet.
- titanium and / or zirconium-containing means that the conversion layer contains at least a layer weight of 1 to 30 mg / m 2 titanium and / or 1 to 30 mg / m 2 zirconium.
- the surface of such a sheet is optionally galvanized, the galvanizing being applied electrolytically or by means of hot-dip dipping. As a result, the corrosion protection of the later composite component is once again significantly improved.
- an adhesion promoter coating is understood to mean a layer consisting of or comprising an adhesion promoter, regardless of the thickness of this layer.
- the layer thickness of the adhesion promoter coating is also different over its length and width and / or the layer consists of several separate sub-layers, as they are e.g. B. arise with an only punctiform or partial area instead of a full-area application of the adhesion promoter.
- a further conversion layer which contains iron and optionally further metal ions such as cobalt and / or nickel, is arranged between the metal-containing and preferably steel-containing or made of steel sheet with an optionally galvanized surface and the titanium-containing and / or zirconium-containing conversion layer.
- the further conversion layer containing iron and optionally further metal ions such as cobalt and / or nickel preferably has a layer weight of 1 to 80 mg / m 2 iron, and layer weights of 1 to 30 mg / m 2 each for the optionally contained metal ions.
- the sheet metal according to the invention with an adhesion promoter coating is produced in a process which, after an optional cleaning and before the application of the adhesion promoter, includes a one or two-stage pretreatment of the sheet metal surface.
- a pretreatment of the sheet metal surface is understood to mean, in particular, the application of a conversion layer.
- a medium is applied to the optionally previously cleaned sheet metal surface, which reacts chemically with the sheet metal surface to form the conversion layer.
- the optional cleaning of the sheet metal surface can in particular include alkaline cleaning and / or degreasing of the sheet metal surface.
- the process for producing the sheet metal with an adhesion promoter coating includes the following steps:
- the method for producing the sheet with an adhesion promoter coating also includes a step of pretreating the sheet with an acidic or basic iron or cobalt before the step of pretreating the metal-containing sheet with the acidic or basic titanium and / or zirconium-containing conversion solution - and / or nickel-containing conversion solution, whereby an iron, cobalt and / or nickel-containing conversion layer is obtained on the sheet metal.
- Both the one-stage and the two-stage pretreatment of the sheet metal surface improves the corrosion protection at the interface between the sheet metal surface and the adhesion promoter coating.
- the sheet metal surface is treated with at least one acidic (pH ⁇ 6) or basic (pH> 8) conversion solution. Due to the high or low pH value of the conversion solution, the thin oxide layers on the sheet metal surface are pickled, so that the reactivity of the sheet metal surface is increased.
- the ions or complexes contained in the conversion solution then react with the metal sheet surface to form a conversion layer, whereby in the case of the one-stage pretreatment a conversion layer is created between the sheet metal and the adhesion promoter and in the case of the two-stage pretreatment two conversion layers are created between the sheet metal and the adhesion promoter become.
- the acidic or basic conversion solution which is used to produce a titanium and / or zirconium-containing conversion layer on the sheet metal contains at least one titanium and / or one zirconium compound.

- a typical conversion solution contains a titanium and / or zirconium-containing complex compound with fluoride ions as ligands and / or manganese ions as counterions.
- the titanium and / or zirconium-containing conversion layer produced in this way therefore contains, for example, hexafluorotitanates and / or hexafluorozirconates.
- a single-stage pretreatment with the titanium and / or zirconium-containing conversion solution can produce a sheet with an adhesion promoter coating which has a significantly improved corrosion resistance compared to conventional sheets with an adhesion promoter coating.
- the corrosion resistance can, however, be increased significantly if, instead of the single-stage pretreatment, a two-stage pretreatment of the sheet metal surface takes place before the adhesion promoter is applied.
- the optionally galvanized sheet metal surface is treated in a first step with an acidic or basic conversion solution that contains iron, cobalt and / or nickel.
- the conversion solution particularly preferably contains iron (II) or iron (III) ions, e.g. B. in the form of iron (II) - or iron (III) nitrate or sulfate.
- iron (II) or iron (III) ions e.g. B. in the form of iron (II) - or iron (III) nitrate or sulfate.
- a chemical reaction takes place between the preferably galvanized sheet metal surface and the iron, cobalt and / or nickel ions from the conversion solution.
- Metallic zinc is oxidized and the more noble iron, cobalt and / or nickel ions are reduced, so that a very thin iron, cobalt and / or nickel-containing layer is deposited on the sheet metal surface.
- the sheet metal surface with the conversion layer created in the first step is treated with an acidic or basic titanium and / or zirconium-containing conversion solution, creating a titanium and / or zirconium-containing conversion layer on the iron, cobalt and / or nickel-containing conversion layer is produced.
- the titanium and / or zirconium-containing conversion solution is preferably of the same nature as described with reference to the single-stage pretreatment, i.e. H.
- the titanium and / or zirconium-containing conversion solution preferably contains one or more complex compounds with a titanium and / or zirconium ion as the central ion and particularly preferably with fluoride ions as ligands and / or manganese ions as counter ions.
- rinsing with fully demineralized water and / or drying can be carried out in order to remove residues of the respective conversion solution from the sheet metal surface .
- the inventive method after the step of pretreating the metal-containing and preferably steel-containing or steel sheet with the acidic or basic iron, cobalt and / or nickel-containing conversion solution, which is used to form an iron, cobalt and / or nickel-containing conversion layer leads on the sheet, and / or after the step of pretreating the sheet or the sheet provided with the iron, cobalt and / or nickel-containing conversion layer with the acidic or basic titanium and / or zirconium-containing conversion solution, which is used to form a titanium and / or zirconium-containing conversion layer performs a step of rinsing and / or drying the sheet provided with the iron, cobalt and / or nickel-containing conversion layer and / or the sheet metal provided with the titanium and / or zirconium-containing conversion layer.
- the sheet metal produced as an intermediate product in the process according to the invention with the titanium and / or zirconium-containing conversion layer arranged thereon and the optional iron, cobalt and / or nickel-containing conversion layer arranged between these is then heated to temperatures above 200 ° C, in particular to temperatures between 220 ° C and 270 ° C heated e.g. B. in a continuous furnace.
- the aforementioned temperatures relate to the sheet metal temperature, the so-called “peak metal temperature”.
- the adhesion promoter coating is laminated onto the still hot sheet metal surface, ie onto the titanium and / or zirconium-containing conversion layer.
- the method according to the invention is preferably carried out as a coil coating method and comprises, in particular after the adhesion promoter has been laminated onto the titanium and / or zirconium-containing conversion layer with the optionally underlying iron, cobalt and / or nickel-containing conversion layer, a further step of winding on the coated and with the adhesion promoter provided sheet, which takes place after an optional step of cooling, in particular by water.
- a preferably steel-containing sheet metal with an adhesion promoter coating and improved corrosion properties is obtained as a semi-finished product for the production of metal-thermoplastic composite components.
- a thickness of the adhesion promoter layer of 15 ⁇ m to 500 ⁇ m has proven to be particularly favorable for the adhesion properties of the thermoplastic on the sheet metal. Within this range, the layer thickness range from 50 ⁇ m to 200 ⁇ m has proven to be particularly preferred.
- coil coating can also be applied to the rear side, ie to the one facing away from the adhesion promoter coating Side of the sheet.
- This has the advantage that process steps can be saved in the further processing of the sheet metal, and forming steps can be improved and / or lubricant-free forming can be implemented.
- the method is also extremely advantageous in terms of process economy, since the application of the Conversion layer (s), the lamination of the adhesion promoter and the optional backside coating can be carried out in one pass.
- the process is particularly economical when the adhesion promoter coating is applied as a film.

- Example 1 Influence of infiltration corrosion in the alternating corrosion test The results of the infiltration corrosion of samples in the cyclic alternating corrosion test VDA 233-102 after various exposure times are shown in FIGS. 2a and 2b.
- Electrolytically galvanized sheet steel was used for all of the samples shown in FIGS. 2a and 2b. However, the tests were carried out in the same way with hot-dip galvanized sheet metal and led to comparable results.
- Some of the samples were then subjected to a one-step pretreatment with titanium and / or zirconium-containing conversion solution.

- the conversion solution was applied with a so-called chemcoater (applied layer weight of titanium: 4.8 mg / m 2 ).
- the sheets were then dried in a continuous oven.
- Another part of the samples was subjected to a two-stage pretreatment, which included a pretreatment with a conversion solution containing iron, cobalt and / or nickel in the first step and a pretreatment with a conversion solution containing titanium and / or zirconium in the second step.
- the bath preparation for the iron, cobalt and / or nickel-containing conversion solution in deionized water contained a conversion solution (4.3% by volume) + 50% NaOH (2.3% by volume).
- the metal sheets were immersed in the approx. 50 ° C warm bath for a period of 9 to 11 seconds, then rinsed twice with deionized water and dried. This was followed by the application of the titanium and / or zirconium-containing conversion solution (corrosion protection agent for metals with a chemcoater) (applied layer weight of titanium: 4.8 mg / m 2 ) and the sheets were dried in a continuous oven.
- thermoplastic adhesion promoter film was then laminated onto the hot sheet metal surface in a heatable lamination unit and the sheets were cooled to room temperature by means of water cooling.
- FIGS. 2a and 2b Exemplary photos of electrolytically galvanized samples are shown in FIGS. 2a and 2b.

- Example 2 Influence of the pretreatment of the sheet metal surface on the adhesive strength
- strips measuring 12.5 mm x 25 mm were cut from polyamide 6 thermoplastic films (PA6 with 60% unidirectional carbon fibers). The unidirectional long fibers lay parallel to the 12.5 mm edge.
- the strips were stored in a drying cabinet at 60 ° C.
- Strips with dimensions of 25 mm ⁇ 100 mm were cut from the sheet metal substrates, these were deburred, degreased with heptane (mixture of isomers) and dried in an upright position. Then tensile shear tests were created from the sheet metal and thermoplastic strips.
- thermoplastic strip 10 (PA6 strip) is fixed by two clamps between a sheet metal strip, the top 8 of which is coated with adhesion promoter, and a sheet metal strip, the underside 9 of which is coated with an adhesion promoter.
- the bonding layer thickness for the carbon fiber reinforced thermoplastic strips was realized through the fiber thickness.
- the lap shear samples were placed in an oven preheated to 260 ° C. and joined by melting the thermoplastic matrix at 260 ° C. for 30 minutes. The temperature was controlled via the thermocouple of the furnace used and the time between reaching the joining temperature and removal from the furnace was defined as the dwell time.
- test specimens were stored for at least 24 h in the room climate so that tensions in the thermoplastic could be relieved and it could change to the "normal state" by absorbing air humidity.
- Some of the hybrid samples were then phosphated in the typical automotive style and coated with cathodic dip painting (KTL). The KTL was then cured at 175 ° C for 25 minutes.
- the tensile shear test was carried out in a standard tensile testing machine based on DIN EN 1465 and the average tensile shear strengths obtained and shown in FIG. 4 are mean values from five parallel samples in each case.
- a comparison of the results of samples a) to d) shows, on the one hand, that the influence of phosphating and cathodic dip painting on the bond strength in the composite is comparatively small and, on the other hand, that the bond strength remains almost unchanged due to the one or two-stage pretreatment.
- the diagonally hatched bars represent the results for the electrolytically galvanized steel sheet
- the horizontally hatched bars represent the results for the electrolytically galvanized steel sheet pretreated in one stage
- the checkered bars represent the results for the two-stage pretreated electrolytically galvanized steel sheet
- the unhatched bars represent the results for the operating material.
- the adhesive strength of the sheet metal pretreated in one and two stages decreases less sharply as a result of aging in the alternating corrosion test than that of the untreated sheet metal and the operating material.
- the sheets according to the invention with one or two conversion layers and the adhesion promoter coating in the composite are therefore also characterized by a reduced decrease in adhesion after aging in the alternating corrosion test.
- Another advantage of the sheets according to the invention is that the adhesive strength after aging in the alternating corrosion test is significantly more homogeneous than in the case of the untreated sheets.
- FIGS. 6 to 9 once again summarize the schematic layer structure of the various coating variants of the sheet according to the invention with an adhesion promoter coating.
- the thermoplastic 10 applied to the adhesion promoter coating is not shown here.
- FIG. 6 shows a first variant with a metal-containing sheet 1, a conversion layer 3 applied to it and an adhesion promoter 2 as a top coating.
- FIG. 7 shows an additional metallic coating 1 1 on the sheet 1 and the conversion layer 3 and the adhesion promoter coating 2 applied to it.
- FIG. 9 shows a layer structure corresponding to FIG. 8, but here the metal-containing sheet 1 again has an additional metallic coating 1 'as corrosion protection on.
- the conversion layer is also based on other elements, e.g. B. silicon is generated.
