Abstract
A protective coating is provided for metallic components of power installations which are in direct contact with the water used as a working medium in steam power stations, in particular. The vaporous working medium not only forms an undesirable film of condensate but also contributes to the destruction of the components, due to the impact of drops. The protective coating eliminates these disadvantages. The protective coating has an inhomogeneous structure including at least two layers which are produced from an amorphous material. The layers have different properties which render the components unwettable and resistant to erosion.
