Abstract: A process for producing a steel component with a metallic, corrosion protection coating and very good mechanical properties may involve directly applying an iron-based alloy to a steel substrate. The iron-based alloy may contain 50-80% by weight of Fe, 0-30% by weight of Mg, 0-5% by weight of Al, 0-5% by weight of Ti, 0-10% by weight of Si, 0-10% by weight of Li, 0-10% by weight of Ca, 0-30% by weight of Mn, and a balance of Zn and unavoidable impurities. The steel substrate that has been coated with the iron-based alloy may then be subjected to hot forming in order to obtain the steel component. A metallic coating that protects against corrosion for steel components to be produced by the process of hot forming can be obtained.

Abstract: A method for producing a metal composite material with an embedded functional structure, in which a build-up of layers comprising a number of layers that are arranged one on top of the other in the vertical direction is produced and pressed, may involve producing the build-up of layers by providing a lower layer comprising a metal substrate, arranging at least in certain portions over the lower layer in a vertical direction an intermediate layer that is in contact with the lower layer, and arranging one or more functional structures respectively in a portion of the build-up of layers. To reduce the risk of increased degradation, before the pressing, the build-up of layers may have the same thickness in the respective portion with the functional structure as in the remaining build-up of layers. Further, a metal composite material with an embedded functional structure may be produced by such a method.

Abstract: A reflector for helio-thermal systems may include a metallic carrier plate and a reflective coating that is applied to the carrier plate and is constructed from at least one metallic reflective layer and at least one protective layer applied to the reflective layer. Such reflectors have high reflective capabilities, are robust in relation to mechanical stress, and can be manufactured cost effectively. Such reflectors are also lightweight and dimensionally stable due to the fact that the carrier plate may be formed from a sandwich plate having at least one nonmetallic intermediate layer disposed between an upper and lower metallic cover plate. The upper cover plate may have a smoothed surface to which the reflective layer can be applied. The smoothed surface prior to the reflective layer being applied may have an arithmetic mean surface parameter Ra of less than 0.03 μm. Methods for manufacturing such reflectors are also disclosed.

Abstract: A process for producing a three-dimensionally shaped steel component from a steel sheet with a metallic coating may involve hot forming the steel sheet into the steel component. The metallic coating may involve an Fe—Al-based alloy. To protect the steel sheet or the steel component against scale formation, the Fe—Al-based alloy may be applied directly to the steel sheet by galvanic coating and/or physical vapor deposition. The coating produced in this way may contain 30-60% by weight Fe, a balance of Al, and, in some cases, 0.1-10% by weight Mg, 0.1-5% by weight Ti, 0.1-10% by weight Si, 0.1-10% by weight Li, and/or 0.1-10% by weight Ca. Before heating the coated steel sheet as part of the hot forming process, the coated steel sheet may have an Fe—Al phase is stable to above 900° C.
