Abstract

A component having a corrosion-resistant and/or oxidation-resistant coating is provided that includes at least one platinum-aluminum substrate area is provided, the component having a substrate surface (11) and a substrate composition based on nickel, with a platinum-aluminum substrate area (12) formed in the area of the substrate surface of the component by precipitating platinum (Pt) and aluminum (Al) on the substrate surface. The platinum-aluminum substrate area (12) has a two-phase structure or duplex structure with finely dispersed platinum-aluminum deposits in a nickel-based mixed crystal in an outer zone (13), and a single-phase structure made of a nickel-based mixed crystal in an inner zone (14) located between the substrate surface (11) of the component and the outer zone (13).
