A multilayer system having at least one anticorrosion layer and a wear protection layer, wherein the anticorrosion layer is formed by a metal nitride or a metal carbonitride which contains at least titanium and magnesium as the metal, wherein the metal nitride or the metal carbonitride further includes at least one rare earth metal, and the wear protection layer is formed by at least one diamond-like metal-free carbon layer. A component having such a multilayer system and a method for producing the multilayer system or the component are also provided.

Multilayer system, component, and method for producing such a multilayer system or component

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.
