According to a further aspect, the present invention relates to a method for producing a steel component and to the steel component obtained according to the method according to the invention. Furthermore, the present invention relates to the use of at least one alkaline earth or transition metal to improve the tribological properties and to lower the coefficient of friction of a cold-formed steel flat product.
- flat steel product means all rolled products whose length is much greater than their thickness. These include steel strips and sheets as well as blanks and blanks derived from them.
- the term choice of an inner Al-Si-containing layer and an outer layer of alkaline earth oxide and / or transition metal oxide means that the layer structure does not have a sharply delimited layer structure, but rather an alloy is present in which the oxygen affinity of the respective components - these are present in the inner or outer layer in an increased concentration.

For example, in the automotive industry as a temperature and corrosion resistant coating, for example, for components such as exhaust systems or heat shields.
