RÉSUMÉ

Carbon plasma flows for deposition of diamond-like films are generated in a vacuum chamber with residual pressure of down to 5·10−5 Torr with the use of four-electrode system with graphite cathode and self-recovering thin-film conductor of an ignition device. The pulse-periodic flows of the carbon arc plasma are considered at discharge current of 4−10 kA, duration of pulses of 100−200 μs and the pulse repetition rate of up to 30 Hz. The form and amplitude of voltage and current of pulses of igniting, supporting and main discharges, and the form of light pulse in various zones of the discharge were measured. Emission spectra of carbon erosive plasma were recorded. The information on reproducibility of the arc discharge of short duration was obtained as well.
