Embodiment Construction
[0036] figure 1 Shown is a micrograph of a core part 100 with a core 102 of steel material and with an Fe—Al—Si coating 104 with a first sublayer 106 and a second sublayer 108 .
[0037] Core 102 is currently steel plate. Coating 104 is used to bond with the aluminum material. Coating 104 has an average of about 1% to about 10% by weight of silicon (Si), iron (Fe), and the remainder aluminum (Al). The first sub-layer 106 is located between the core portion 100 and the second sub-layer 108 . The first sublayer 106 has at least about 42% by weight iron (Fe), at least about 11% by weight silicon (Si), and the remainder at most about 45% by weight aluminum (Al). The coating 104 can be applied by PVD method, or by other methods such as hot-dip method and the like. First sublayer 106 has a thickness of at most approximately 3.5 μm, in particular at most approximately 3 μm. The second sub-layer 108 is disposed on the first sub-layer 106 and forms the outer side of the core porti...

Abstract
A coating (104) for a carrier material composed of a steel material for connection to an aluminum material, the coating (104) having a first sublayer (106) on the core part side and a second sublayer (106) on the outside layer (108), wherein the coating layer (104) has an average of about 1 wt% to about 10 wt% silicon (Si), iron (Fe) and the remainder aluminum (Al); the first sublayer ( 106) having at least about 42 wt % iron (Fe), at least about 11 wt % silicon (Si), and at most about 45 wt % remaining aluminum (Al); the first sublayer (106) has at most about a thickness of 3.5 μm, in particular at most about 3 μm; the second sublayer ( 108 ) has about 1 wt % to about 10 wt % silicon (Si), in particular about 7 wt % to about 10 wt % silicon ( Si) and the remaining aluminum (Al); the second sublayer (108) has a thickness of about 5 mm to about 95 mm. A core portion (100) for manufacturing a composite part, the core portion (100) having a carrier material (102) of steel material and such a coating (104). A composite part, wherein the composite part has an outer part connected to the core part (100) according to such a core part (100) and an aluminium material. A method for making such a composite part.
Description
technical field [0001] The invention relates to a coating for a carrier material consisting of a steel material for joining to an aluminum material, the coating having a first sublayer on the core side and a second sublayer on the outside. The invention also relates to a core for the manufacture of composite components. Furthermore, the invention relates to a composite component. In addition, the invention relates to a method for producing composite components. Background technique [0002] A method for producing composite bodies from cast bodies and cast materials is known from DE 10 2004 031 164 A1. A coating system consisting of two layers is proposed here. The two layers have different compositions and melting temperatures. The two layers are applied in the form of droplets by spraying, wherein a joined or mixed layer structure can be produced by the independent solidification of the components of the two layers. The first layer, mostly adjacent to the component, is...
