Abstract
A method for producing a contact region for a layer of an electrical heating device for a motor vehicle may include providing the layer made of a thermally sprayed, electrically conductive material, providing a laser beam having a focus, introducing a powder of an electrically conductive material into the focus of the laser beam, and thereby melting the powder, applying the molten powder to a region of the layer, and thereby forming the contact region from the electrically conductive material for making contact with the layer.
Claims14
A method for producing a contact region for a layer of an electrical heating device for a motor vehicle, comprising the steps of:
- providing the layer made of a thermally sprayed, electrically conductive material,
- providing a laser beam having a focus,
- introducing a powder of an electrically conductive material into the focus of the laser beam, and thereby
- melting the powder,
- applying the molten powder to a region of the layer, and thereby
- forming the contact region from the electrically conductive material for making contact with the layer.
An apparatus for an electrical heating device for a motor vehicle, comprising:
- a layer made of a thermally sprayed, electrically conductive material, and
- a contact region for making electrical contact with the layer, which contact region is formed from an electrically conductive homogeneous material and is connected to the layer in a form-fitting and/or integral manner.
