The invention relates to a method for producing, in a continuous process, a coating on profiled components made from steel sheet. For this purpose, hot-stamped profiled components are provided and are loaded onto transport system. On the transport system, the profiled components are subjected to mechanical cleaning. The mechanical cleaning, more particularly a blasting treatment, is followed by an antioxidation treatment of the profiled components, before a metal powder is applied to the profiled components in such a way that there is metal powder over the full surface of the profiled components. Thereupon, the profiled components are transferred, on the transport system, into a continuous furnace and thermally treated in such a way that the coating is formed by a diffusion process between the profiled components and the metal powder. After exiting the continuous furnace, the profiled components are unloaded from the transport system.

The invention relates to a device for producing a structure-borne sound vibration in the event of an impact of a collision object with a vehicle. For this purpose, an element (1a, 1b) that can be vibrated mechanically and a plurality of mechanical excitation elements (2a, 2b) or a preferably continuous excitation profile are arranged relative to each other in such a way that the excitation elements (2a, 2b) or the excitation profile or alternatively the element (1) that can be vibrated are slid mechanically relative to each other by means of an impact of the vehicle, and the excitation elements (2, 2a, 2b) or the excitation profile causes a mechanical excitation of the element (1) that can be vibrated. The sequence of excitations or the continuous excitation thus leads to a significant and measurable structure-borne sound vibration, which signifies the severity and speed of the impact or of the deformation. A particular advantage of this embodiment is that the element that can be vibrated can be reversed, at least in the event of small impact events, and that the device can therefore be reused. If a continuous excitation profile is used, the excitation can be made to have a significantly narrower band. Thus, interfering high-frequency components are significantly reduced. At least two devices having different characteristics are preferably arranged on a vehicle.

According to the method, a printed circuit board (7) that is severed from the strip material (4) comprising coated, high-strength boron steel is homogeneously heated in a furnace (11) having a plurality of temperature zones (8, 9, 10) first in a first zone (8) to a temperature of approximately 830ºC to 950ºC and maintained at said temperature level for a define time (t). Thereafter, a region (12) of a first type of the printed circuit board (7) is cooled in a second zone (9) of the furnace (11) to a temperature of approximately 550ºC to 700ºC and maintained at said lowered temperature level for a defined time (t1). At the same time, a region (13) of a second type of the printed circuit board (7) in a third zone (10) of the furnace (11) is maintained at a temperature level of approximately 830ºC to 950ºC during a time (t2). After said heat treatment, a printed circuit board (7) is formed into a formed component (1) in a thermoforming process. The strip material is pre-coated with an aluminum silicon diffusion alloy.

Abrégé

The invention relates to a gas-dynamic pressure wave machine for charging an internal combustion engine comprising a cell rotor (1) rotatably supported in a housing and located between an inlet for charge air and an exhaust line for combustion gases, wherein the external circumference of the cell rotor (1) increases from the exhaust gas side (3) to the charge air side (4). The height of a cell of the cell rotor (1) in the radial direction remains constant in the longitudinal direction of the cell rotor (1), while the cross-sectional area of the individual cells increases from the exhaust gas side to the charge air side.
