Abstract: The invention relates to a sintered component (1), in particular an annular sintered component (1), with a toothing (2), wherein the toothing (2) comprises teeth (3) with tooth bases (6) and tooth flanks (4). All of the teeth (3) and tooth bases (6) of the toothing (2) comprise a plasma nitrided or plasma nitrocarburized layer (7), wherein the tooth bases (6) have a tooth base fatigue strength ?F lim according to DIN 3990 of at least 200 MPa.

Abstract: The invention describes a process for the production of a coating (6) on the basis of at least one material selected from a group comprising silicon, germanium, and the oxides SiOx or GeOx of these elements, whereby these are doped where applicable and produced specifically amorphised, on at least a subsection of a surface (3) of a metallic substrate (2), whereby the concentration of nitrate is increased in the substrate (2) where applicable prior to precipitation of the coating (6) at least in the area of the subsection. This subsection is subjected to oxidation prior to precipitation of the coating (6).
