Abstract (en)
[origin: WO2021219511A1] The invention relates to a component (1) with a wear protection coating, said component consisting of a steel alloy, in particular a fuel injection system component, the tribologically stressed surface of which is at least partly coated with a hard outer wear protection coating (2) at least partly using a plasma method, said wear protection coating being applied onto a metal adhesive layer (3). The metal adhesive layer (3) is applied onto an Fe buffer layer (4) which is deposited onto the surface of the component (1) in order to separate the component (1) surface, which acts as the diffusion front, from the adhesive layer (3).
