| Summary: | The results of investigations of applicability of the method of high-frequency short-pulsedplasma-immersion ion implantation and (or) coating deposition using vacuum-arc and ablationplasma to conductive and dielectric substrates are presented. It is shown that ion implantation with the ion sputtering compensation by coating deposition from plasma and ion-assisted coating deposition can be realized for the metal and dielectric samples through alteration of the negative bias potential within 0-4 ⋅ 103 V, with the pulse repetition rate of (1-4.4) ⋅ 105 pps, pulse duration 0.5-2 μs and duty factor of 0.1-0.9. It is experimentally established that at coating deposition from ablation plasma obtained by the influence of the high-intensity ion beam (j = 3 ⋅ 102 A/m2, E = 350 keV, τ = 90 ns) on the target, the micro-arc effects on the substrate surface are observed at a dc bias potential of more than -60 V. The transition to pulses of 0.5 μs duration enabled to increase the bias potential up to -4 kV. The possibility of application of the high-frequency, short-pulse bias potentials for the formation of coatings from vacuum-arc and blation plasma with high adhesive strength and improved exploitation characteristics is discussed |
