Abstract: A method for carbon deposition using a pulsed, plasma-supported vacuum arc discharge, having an anode, a target cathode made of carbon, a pulsed energy source and at least two ignition units. The at least two ignition units are positioned in the edge area of target cathode and each have two planar metallic electrodes and a planar ceramic insulator positioned between the electrodes. The planar shape of ignition units and their positioning on target cathode enables homogeneous utilization of the entire target surface and homogeneous coating of workpieces.

Abstract: A pump piston and/or elements sealing the pump piston, in particular a sealing ring of elastomeric material with an additionally applied coating are/is proposed. To improve the durability characteristics, the pump piston and/or the elements sealing the pump piston have a coating which is formed at least predominantly of halogen-, silicon-, carbon-containing and/or metal-organic monomers. Furthermore, a device and a method for coating an object of elastomeric material utilizing a plasma are proposed.

Abstract: A method for producing a nanostructured, in particular a ceramic-like functional coating on a substrate is described. To that end, using at least one plasma source, a pulsed plasma is produced with which a matrix phase and at least one nano-scale interstitial phase embedded in it are deposited on the substrate via a material input. Preferably a plurality of pulsed plasma sources that are time-correlated or synchronized with each other are used. Also proposed is a nanostructured functional coating, in particular one producible by this method, which is free of chlorine and/or sulfur, and which contains at least one metal and/or at least one element selected from the group oxygen, hydrogen, nitrogen, carbon, helium, argon or neon.

Abstract: A subassembly of an internal combustion engine is described, in particular an injection system or a fuel injector having a tribologically stressed component, in particular an injection needle, having a surface area which moves relative to a mating body during operation and is thus tribologically stressed, the surface area having an at least mostly an inorganic hard material coating. The subassembly is suitable in particular for use in an internal combustion engine which is operated with a dry gas such as natural gas or hydrogen as the fuel or under oil-free and/or water-free combustion conditions. In addition, a gas engine having such a subassembly is described.

Abstract: A device is proposed for the ceramic-type coating of a substrate (2), means being provided for depositing a material (5, 7), especially by using a plasma (8), on a surface of the substrate (2), which, in contrast to the related art, allows a ceramic coating (3) of comparatively temperature-sensitive substrates (2). According to the present invention, this is achieved in that an energy source that differs from a material source (4, 6) of the material (5, 7) provided for the coating, is provided for the locally defined energy input into the material (3, 5, 7, 8) present in front of and/or on the surface.
