“…To produce pulsed ion beams having energy of 300 keV and current density of up to 200 A/cm 2 , a magnetically insulated diode is used in the TEMP accelerator in a magnetic-insulation mode applying an external pulsed transverse magnetic field [26]. The major advantages of this type of diode over other diode systems are long service life and ion beam pa-rameter stability.…”

-An innovative concept in the development of advanced coating deposition and ion implantation method including an application of filtered DC metal plasma or ablation plasma and highfrequency short-pulsed negative bias voltage with a duty factor in the range 10-99% are considered.It was shown that plasma based ion implantation as well as ion-assisted coating deposition may be realized for metal and dielectric samples by variation of negative bias potential in the range of 0-4 · 10 3 V, pulse repetition rate smoothly adjusted in the range of (2-4.4) · 10 5 pps and pulse duration in the range of 0.5-2 µs.It was experimentally shown that at coating deposition from ablation plasma obtained by high intensity ion beam (j = 300 A/cm 2 , E = 350 keV, τ = 90 ns) influence on the target, the breakdown of the plasma sheet occurred at dc negative bias potential on a substrate more than 60 V. The transfer to 0.5 µs duration pulses allowed us to increase the bias potential up to -4 kV.

“…This is due to its ability to modify surface layers without changing the physicochemical state of the materials in the bulk of the parts. The effectiveness of the application of powerful pulsed ion beams and ion implantation for processing products from titanium and its alloys has already been proven in many works [23][24][25][26][27][28][29][30][31][32][33][34][35][36]. It was shown that, as a result of pulsed ion beam exposure, it is possible to reduce surface roughness [23], form a gradient microstructure [26,27], increase mechanical properties [28][29][30][31][32][33], and improve corrosion resistance [34,35].…”

The effect of surface modification of Ti-6Al-4V samples manufactured by electron beam melting (EBM) using a pulsed carbon ion beam is studied in the present work. Based on the results of XRD, SEM, and TEM analysis, patterns of changes in the microstructure and phase composition of the EBM Ti-6Al-4V alloy, depending on the number of pulses of pulsed ion beam exposure, are revealed. It was found that gradient microstructure is formed as a result of pulsed ion beam irradiation of the EBM Ti-6Al-4V samples. The microstructure of the surface layer up to 300 nm thick is represented by the (α + α”) phase. At depths of 0.3 μm, the microstructure is mixed and contains alpha-phase plates and needle-shaped martensite. The mechanical properties were investigated using methods of uniaxial tensile tests, micro- and nanohardness measurements, and tribological tests. It was shown that surface modification by a pulsed ion beam at an energy density of 1.92 J/cm2 and five pulses leads to an increase in the micro- and nanohardness of the surface layers, a decrease in the wear rate, and a slight rise in the plasticity of EBM Ti-6Al-4V alloy.

Titanium coatings are deposited on a Si substrate by their deposition from ablation plasma pro duced by irradiating a Ti target with high power ion beams. The dependences of the adhesion, nanohardness, Young's modulus, and friction coefficient on the distance between the sputtered target and the substrate and on the thickness of the coating are studied for thin film titanium coatings. The formation of a transition layer with an alternating content of Ti is found to increase coating adhesion.
