Abstract
A steam turbine component coated with a protective layer can be exposed to hot vapor. The component has a metallic base body, to which the protective layer is bonded by diffusion in order to increase the resistance of the base material to oxidation. The protective layer contains aluminum and has a thickness of less than 50 &mgr;m. The protective coating can be formed by applying an aluminum pigment to the base body and maintaining the component at a predetermined temperature.
