A coating plant for coating a planar object, for example a strip conveyed using transport rollers, is disclosed. The coating plant includes a vacuum chamber and a device for vapor deposition of a material. The device for vapor deposition includes an evaporation portion and a nozzle portion, wherein the nozzle portion includes a nozzle having a nozzle outlet. The nozzle outlet can have an extension. The nozzle is rotatably mounted.

Coating plant for coating a planar object and a method for coating a planar object

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.

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&#x2014;Al-based alloy. To protect the steel sheet or the steel component against scale formation, the Fe&#x2014;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&#x2014;Al phase is stable to above 900&#xb0; C.

A flat steel product having a base layer of a steel material and a multilayer coating applied thereto, and a method for producing the flat steel product. The method having the following steps: providing a steel base layer; applying a zinc layer to the base layer by electrolytic coating; applying an aluminum layer to the surface of the zinc layer, wherein no treatment is made to the surface of the zinc layer in regard to the oxides and sulfides present thereon at the end of the electrolytic zinc coating step or occurring during the course of the aluminum coating step; applying a magnesium layer to the aluminum layer; and subsequently heat treating the flat steel product in such a way that an MgZnlayer forms in the coating above the Al layer.
