A coating for a carrier material made of a steel material for joining to an aluminum material includes a first sublayer on the core part side and a second sublayer on the outside. On average, the coating includes approximately 1 to 10 wt. % silicon and iron, the remainder being aluminum. The first sublayer at least approximately includes 42 wt. % iron, 11 wt. % silicon, and no more than approximately 45 wt. % aluminum, which constitutes the remainder, and has a thickness of no more than approximately 3.5 &#x3bc;m. The second sublayer includes approximately 1 to 10 wt. % silicon, the remainder being aluminum, and has a thickness of approximately 5 to approximately 95 &#x3bc;m.

The invention relates to a hot forming tool for hot forming a metal workpiece, having at least two dies which may be moved relative to one another for forming the workpiece, and having a cooling device by means of which the workpiece may be cooled in the hot forming tool from a first, higher temperature to a second, lower temperature. To improve the hot forming tool, it is provided that the hot forming tool is equipped with a separating device by means of which a separating operation may be carried out on a workpiece present in the hot forming tool. The invention further relates to a method for hot forming.

The invention relates to an energy absorption device which can be arranged to absorb energy by deformation between a support structure of a vehicle and a damper, the energy absorption device carrying a deformable main profile which has a hollow body-type cross-section. The aim of the invention is to improve an energy absorption device of the aforementioned type in such a manner that the energy can be well carried off even if the forces produced by an accident impact the energy absorption device at an angle. For this purpose, a deformable supplementary profile is provided on the cross-section of the main profile.
