At least one electrode is connected as a cathode, and at least one as an anode. Direct current pulses are supplied at a frequency of 10-150 kHz, with pole changes taking place in such a way that each electrode on time average, is switched as cathode and anode an equal number of times. Also claimed (below) is an apparatus for implementation of the proposed method. USE - In vacuum coating technology. ADVANTAGE - Improved energy introduction into the discharge process.de608667670620patent1997-19702187
