Abstract: A sealing arrangement for sealing a first housing part with respect to a second housing part is arranged in an annular groove between the two housing parts. The sealing ring has a cross-section which abuts in a central area as an O-ring on opposite sides on the two housing parts. In addition, the cross-section has at least two sealing ears which extend from the central area of the cross-section into corners of the annular groove.

Abstract: A method for producing a housing for electronics in which the housing is formed by a first housing element and a second housing element and in which the housing elements are composed of aluminum or an aluminum alloy. The method further includes connecting the housing elements to one another by welding so that the housing elements are held tightly together. The method also includes producing at least one of the housing elements by a die casting method in which gas that is created in the die-casting method is evacuated from the housing element by helium gas.

Abstract: The invention relates to a method (5) for producing a housing (1) for electronics that are used to control an electric motor, wherein the housing (1) is formed by a first housing element (30) and a second housing element (40). According to the invention, the housing elements (30, 40) are composed of aluminum or an aluminum alloy. Furthermore, at least one of the housing elements (30, 40) is created by means of a die-casting method (52). The housing elements (30, 40) are connected to each other tightly, in particular in a fluid-impermeable manner, by means of welding (60).

Abstract: The invention relates to known housing seals of two housing parts lying against each other, a first housing part (1) having a first sealing surface (6) and a second housing part (2) having a second sealing surface (7), which housing seals are equipped with a seal (15), which is inserted into a groove (10) in the first sealing surface (6) of the first housing part (1), wherein the groove (10) is covered by the second sealing surface (7) of the second housing part (2). According to the invention, in order to prevent crevice corrosion, the groove (10) has an opening (11) between the sealing surfaces (6, 7), which is used to ventilate the groove (10) having the inserted seal. The invention is intended for water pumps, in particular for auxiliary water pumps of motor vehicles.

Abstract: Permanent magnet (10), containing at least one metal component (13) from the group of the rare earth metals, comprising a first coating film (20), which forms a cathodic protection against corrosion for the permanent magnet (10), the first coating film (20) containing a metal (23) which is more electronegative in the electrochemical series than the metal component (13) of the permanent magnet (10), wherein a second coating film (30), which is embodied in an electrically insulating fashion, is applied on the first coating film (20).
