Beschreibung
Zusammenfassung:	A component with a component (1) of low-alloy steel and/or heat-treatable steel is provided, wherein the component (1) is at least partially coated with an aluminum diffusion layer (10) and an aluminum oxide layer (14) is applied to the aluminum diffusion layer (10), wherein the layer thickness of the aluminum diffusion layer (10) is 1-200 μm, wherein the aluminum diffusion layer (10) has an aluminum content, based on the total weight of the aluminum diffusion layer, of 10 wt. % above the aluminum content of the steel up to a maximum concentration, wherein the aluminum content in the aluminum diffusion layer (10) increases in the direction of the interface (12) between the aluminum diffusion layer (10) and the aluminum oxide layer (14) from 10% by weight up to the maximum concentration, and wherein the maximum concentration is 11-60% by weight.
