    Abstract

    A method for shielding components includes the steps of providing a component and applying at least one coating region, designed to shield from a magnetic and/or an electrical field, to the component by a thermal and/or kinetic spraying method such that a first arrangement space is shielded from a second arrangement space.

    Claims

    1.-12. (canceled)

    13. A method for shielding components, comprising the steps of: providing a component; and applying to the component a coating region by a thermal and/or a kinetic spraying method, wherein the coating region is a magnetic field shield and/or an electrical field shield.

    14. The method according to claim 13, wherein the spraying method is arc wire spraying or cold gas spraying.

    15. The method according to claim 13, wherein the coating region has a thickness in a range from 50 to 800 μm.

    16. The method according to claim 13 further comprising the step of accelerating a coating material that forms the coating region to a speed greater than 100 m/s.

    17. The method according to claim 13 further comprising the steps of: simulating or calculating a magnetic field and/or an electrical field; and positionally accurately applying the coating region based on the simulating or calculating.

    18. A housing, comprising: a housing wall which defines a first arrangement space and a second arrangement space; and a coating region disposed on the housing wall, wherein the coating region is a magnetic field shield and/or an electrical field shield, wherein the coating region is positionally accurately arranged and dimensioned such that the second arrangement space is shielded with respect the first arrangement space, and wherein the coating region is a thermal sprayed and/or a kinetic sprayed coating.

    19. The housing according to claim 18, wherein the coating region is disposed on an inside of the housing wall.

    20. The housing according to claim 18, wherein the coating region is disposed on an outside of the housing wall.

    21. The housing according to claim 18 in combination with a power electronics system disposed in the second arrangement space.

    22. The housing according to claim 18 wherein the housing is a metal casted component.

    23. The housing according to claim 22, d herein the housing is formed as one part.

    24. A vehicle component produced by the method according to claim 13.

    25. The vehicle component according to claim 24, wherein the vehicle component is a chassis component.

    Description

    BRIEF DESCRIPTION OF THE DRAWING

    [0031] FIG. 1 shows a schematic diagram of an embodiment of a housing.

    DETAILED DESCRIPTION OF THE DRAWING

    [0032] FIG. 1 shows a housing 10 by way of example, comprising an arrangement space 21, an arrangement space 22 and an arrangement space 23. The arrangement space 21 serves for example for arranging an electric motor (not shown here), the arrangement space 22 serves for arranging a transmission. The arrangement space 23 is formed as a protective space 30. This space serves, for example, for arranging a power electronics system, which is intended to be protected as far as possible from any electromagnetic fields from the arrangement space 21. Provided for this purpose are coating regions 40, which are applied directly to a housing wall 12 of the housing 10.

    [0033] In particular, the housing wall 12 is coated by means of a spraying method, in particular a thermal spraying method, such as arc wire spraying or else cold gas spraying. The housing wall 12 is produced for example from aluminum, while the coating regions 40 are formed from a ceramic (Al2O3) or a magnesium material. The housing 10 is advantageously cast, in particular cast integrally or as one part, in other words is not put together. It is evident that the coating regions 40 may be arranged both on the inside and the outside of the housing wall 12, whereby not only with regard to the positioning but also with regard to the effectiveness of the shielding there are almost no limits.
