Zusammenfassung:This invention relates to a component of an iron, cobalt or nickel-base alloy with a protective arrangement to prevent aluminizing or chromizing during gas diffusion coating, with a first layer as an interlayer and a second layer as a getter layer for reaction gases, where the first layer is a slip casting layer composed of oxide ceramic particles carried in a low-carbon vehicle free from halide, and the second layer is a metal layer or a metallic slip casting layer. The metal layer contains at least 50% by weight of the base-metal fraction of the component and exhibits all major alloy constituents of the component. The metal layer may be a sintered metal shape.
