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 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.

Abstract: A cost-favorable process for production of corrosion-resistant sheet steel products, having good characteristics of use for certain application purposes includes applying a zinc-containing coating by electro-galvanizing a flat steel product, finally cleaning mechanically and/or chemically the flat steel product, applying a magnesium-based coating to the finally cleaned zinc-containing coating by means of vapour deposition, and heat treating the coated flat steel product to form a diffusion or convention layer between the zinc-containing coating and the magnesium-based coating at a temperature of 320 ° C. to 335 ° C. under normal atmosphere.
