摘要： A hard carbon coating and a method to improve its adhesion on components and tools subjected to high loads or subjected to extreme friction, wear and contact with other parts. The metal carbide transition layer is situated between the adhesivepromoting layer deposited directly onto the substrate surface and a top hard carbon coating. The metal carbide transition layer has a denser microstructure and improved mechanical properties in order to resist failure by spalling.

摘要： An assembly for cathodic arc deposition of a material onto an article. The assembly includes a chamber for receiving an article to be coated and a rotating target. The rotatable target has a surface from which a plasma material is ejected. An anode ring is positioned a first distance from the surface of the rotatable target. The anode ring has an opening with a central axis that is parallel to a rotational axis of the rotatable target and offset a second distance from the rotational axis. A spark device is disposed in the chamber for generating an arc on the surface of the rotatable target. The assembly configured to direct a stream of charged particles ejected from the surface of the target through the opening of the anode ring to the article to be coated.

摘要： Method for producing a mechanically and preferably machined cast iron or grey cast iron surface, in particular on a brake disc, with increased wear and corrosion resistance, characterized in that said surface is subjected to a water jet treatment—usually according to the so-called fluid jet process, which is adjusted so that it completely or at least partially clears the cavities opened by the machining, which contain a graphite inclusion surrounded by the basic structure, so that in the latter case the level of the graphite inclusion lies below the outer surface of the basic structure surrounding the cavity, whereupon a diffusion layer is applied by nitrocarburizing and an oxide layer is applied on the diffusion layer.
