Abstract
A component (), in particular for a valve train system, having a substrate () and a layer system () applied at least in parts to the substrate (), wherein the layer system () includes a friction-reducing and wear-reducing protective layer () for forming a component surface, wherein the protective layer () has at least one first sub-layer () made of doped tetrahedral amorphous carbon, which includes sp-hybridized carbon having a mole fraction of at least 50%, wherein the first sub-layer () contains oxygen in a concentration in the range from 0.1 at % to 3.0 at % and hydrogen in a concentration in the range from 0.1 at % to 15 at %, and wherein the first sub-layer () has one or more of the following dopants in a concentration in the range from 0.03 at % to 15 at %: chromium, molybdenum, tungsten, silicon, copper, niobium, zirconium, vanadium, nickel, iron, silver, hafnium, fluorine, boron and nitrogen. A method for producing such a component () is also provided.
