  • Publication number: 20140023856
    Abstract: The invention relates to a method and a device for applying a coating to a substrate, where a plasma jet of a low-temperature plasma is produced by conducting a working gas through an excitation zone. The plasma jet is directed at the substrate, and plate-shaped particles having an average thickness between 10 and 50,000 nanometers and a shape factor in a value range from 10 to 2000 are fed into the plasma jet. The plate-shaped particles are fed into the plasma jet by means of a carrier gas. The plasma jet is produced by exciting the working gas by means of an alternating voltage or a pulsed direct voltage.
