Abstract:
1. A process for coating of at least one electrically conducting substrate or a substrate that has been coated so as to be electrically conducting, the process comprising the steps of: placing a gas in a region of an electric discharge; restricting the discharge region on at least two opposite sides by surfaces to be coated, wherein the surfaces to be coated are supplied by one of two flat, parallel substrates and at least one continuously moving band-shaped substrate and wherein the surfaces to be coated form a hollow cathode used to enable a hollow-cathode glow discharge; and coating the surfaces to be coated by a hollow-cathode glow discharge, said discharge activated only by at least one of a DC voltage, a pulsed DC voltage, and an AC voltage having a frequency of up to 50 MHz.
