Abstract (en)
[origin: WO2020078505A1] The invention relates to a component (100), in particular for a valve train system, comprising a substrate (3) and a layer system (1) applied to the substrate (3) at least in parts, wherein: the layer system (1) comprises a friction- and wear-reducing protective layer (2) for forming a component surface; the protective layer (2) comprises at least one first sub-layer (4, 4a) of doped tetrahedral amorphous carbon, which comprises sp3-hybridized carbon at a mole fraction of at least 50%; the first sub-layer (4, 4a) contains oxygen at a concentration in the range of 0.1 at% to 3.0 at% and hydrogen at a concentration in the range of 0.1 at% to 15 at%; and the first sub-layer (4, 4a) comprises one or more of the following dopants at a concentration in the range of 0.03 at% to 15 at%: chromium, molybdenum, tungsten, silicon, copper, niobium, zirconium, vanadium, nickel, iron, silver, hafnium, fluorine, boron, nitrogen. The invention further relates to a method for producing a component (100) of this type.
