A process for surface preparation of a substrate (2), which comprises introducing or running a substrate (2) into a reaction chamber (6, 106). A dielectric barrier (14, 114) is placed between electrodes (1, 10, 110). A high-frequency electrical voltage is generated, to generate filamentary plasma (12, 112). Molecules (8, 108) are introduced into the reaction chamber (6, 106). Upon contact with the plasma, they generate active species typical of reacting with the surface of the substrate. An adjustable inductor (L) placed in parallel with the inductor of the installation is employed to reduce the phase shift between the voltage and the current generated and to increase the time during which the current flows in the plasma (12, 112). |
