Abstract
Components suitable for chemically aggressive environments are disclosed, as well as methods for producing the components. One component may include a substrate having at least one surface having a layer system, which may include an amorphous carbon layer. The layer system may include at least one metallic intermediate layer which is arranged between the substrate and the amorphous carbon layer. The metallic intermediate layer may include titanium, a titanium alloy, nickel, or a nickel alloy. A two-layer bonding layer may be arranged between the at least one intermediate layer and the substrate and a first bonding layer composed of NiP. A second bonding layer composed of a nickel-chromium alloy or a nickel-vanadium alloy may also be present. The amorphous carbon layer may form an outer layer of the layer system facing away from the substrate and may comprise at least one amorphous hydrogen-containing carbon layer.
