摘要： Magnetron discharges are pulse-operated to avoid the so-called “arcing”. In the case of magnetron discharges from alternating current-fed magnetrons, the process is limited to the minor power of the energy supply because of the load-carrying capacity of the required electric components. When the magnetron discharges are fed by direct current, their effectiveness deteriorates because of the deposition of layers on the anode surfaces. The new process should enable a high supply power and prevent arcing. In magnetron discharges with at least two magnetron electrodes, the energy is supplied in such a way that at least one magnetron electrode is a cathode or anode and a number n1 of direct current pulses of said polarity is supplied. The poles of at least one magnetron electrode are then reversed and a number n2 of direct currents of this polarity are supplied. The process is carried on in this manner, the frequency of the direct current pulses being higher than that of the polarity reversals. The energy supply effectiveness is thus improved. This process and system enable the production of layers having the most different properties, for example for the glass, packaging, electronic, and machine construction industries.
