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.
