WEAR AND/OR FRICTION REDUCTION BY USING MOLYBDENUM NITRIDE BASED COATINGS

摘要

The present invention relates to a component comprising a substrate surface coated with a coating comprising at least one MoN layer having a thickness not less than 40 nm, characterized in that between the substrate surface and the at least one MoN layer: i) a substrate surface hardened layer is comprised, which is a hardened, nitrogen-containing substrate surface layer that is the result of a nitriding treatment carried out at the substrate surface and has a thickness not less than 10 nm, preferably not less than 20 nm and not greater than 150 nm, and/or ii) a layer system composed of more than 2 MoN layers and more than 2 CrN layers is comprised, wherein the MoN and CrN layers forming the layer system are individual layers deposited alternate one on each other forming a multilayer MoN/CrN coating film.
