    • The invention relates to a method for coating the surface of a light metal substrate, said method comprising the following steps: A. the light metal substrate is prepared and optionally the substrate surface to be coated is cleaned, B. the substrate surface optionally cleaned in step A is coated in a plasma polymerisation reactor by means of plasma polymerisation. In step B, at least one organosilicon compound and (a) no other compound or (b) other compounds is/are used as precursor(s) for the plasma, and the light metal substrate is arranged in the plasma polymerisation reactor such that (i) it is located between the region wherein the plasma is formed and the cathode is arranged, or (ii) it acts as a cathode. The invention is characterised in that the method is carried out in such a way that the coating produced by the method comprises: between 5 and 20 atom %, preferably between 10 and 15 atom %, of a carbon part that can be determined by XPS measurement, in relation to the total amount of carbon, silicon and oxygen atoms contained in the coating, a yellow index, determined according to ASTM D 1925, of = 3, preferably = 2.5, and a hardness, to be measured by means of nanoindentation, of between 2.5 and 6 GPa, preferably between 3.1 and 6 GPa.

    • The invention relates to a method and a series of devices for dry cleaning, activating, modifying, coating, and biologically decontaminating (degerming, disinfecting, sterilizing) surfaces by means of an atmospheric pressure plasma generated using a surface barrier discharge. The invention is used for dry cleaning, activating, coating, modifying, and biologically contaminating surfaces by means of an atmospheric pressure plasma generated in a defined, flowing gas atmosphere by a surface barrier discharge, comprising a high-voltage electrode (5) that is covered with a dielectric or ferroelectric material (4), an electrically conducting grounded contact electrode (2), a high-voltage supply (7), a gas supply (8), and a gas nozzle (1) encompassing a gas outlet (12). Said gas nozzle is located in the direct vicinity of the grounded contact electrode, is integrated into the contact electrode, or acts as the grounded contact electrode. Furthermore, the gas outlet is designed such that a discharged gas flow is directed to the contact point of the grounded contact electrode. The method is characterized in that the contact electrode including the gas nozzle and the material that is to be treated are moved relative to one another.
