Patent number: 10933617Abstract: 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.Type: GrantFiled: March 1, 2016Date of Patent: March 2, 2021Assignees: THYSSENKRUPP STEEL EUROPE AG, thyssenkrupp AGInventors: Jan-Eric Ehlers, Roman Glass, Bernd Schuhmacher

Patent number: 10704112Abstract: 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.Type: GrantFiled: May 4, 2015Date of Patent: July 7, 2020Assignees: ThyssenKrupp Steel Europe AG, ThyssenKrupp AGInventors: Bernd Schuhmacher, Christian Schwerdt, Axel Schrooten, Ralf Bause

Patent number: 10365463Abstract: 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 ?m. Methods for manufacturing such reflectors are also disclosed.Type: GrantFiled: November 7, 2014Date of Patent: July 30, 2019Assignees: THYSSENKRUPP STEEL EUROPE AG, THYSSENKRUPP RASSELSTEIN GMBHInventors: Bernd Schuhmacher, Stephan Drewes, Karl-Heinz Kopplin, Winfried Höhn, Lothar Patberg, Mark Hirt

Patent number: 10323292Abstract: 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.Type: GrantFiled: April 29, 2015Date of Patent: June 18, 2019Assignees: ThyssenKrupp Steel Europe AG, ThyssenKrupp AGInventors: Bernd Schuhmacher, Christian Schwerdt, Axel Schrooten, Ralf Bause

Patent number: 9088011Abstract: A bipolar plate which can be produced particularly economically for a fuel cell, with which a high degree of efficiency is guaranteed over a long service life. The bipolar plate has a core layer consisting of a steel material, the surfaces of said core layer, which are associated with the respective electrolyte carriers of the fuel cell, having a corrosion protection layer, protecting the core layer against corrosion. The corrosion protection layers consist of a metal material and extend on both sides over the whole surface of the core layer. At the same time the corrosion protection layers are in turn coated over the whole surface with an electrically conductive functional coating, which is essentially entirely impermeable for the metal ions emerging from the core layer and/or the corrosion protection layers. The invention likewise relates to at least one fuel cell comprising a bipolar plate according to the invention.Type: GrantFiled: July 3, 2008Date of Patent: July 21, 2015Assignee: ThyssenKrupp Steel Europe AGInventors: Stefan Wischmann, Horst Walter Tamler, Roland Wunderlich, Michael Steinhorst, Krasimir Nikolov, Nicole Weiher, Jens-Ulrik Becker, Stefan Peter Puls, Bernd Schuhmacher
