“…Here dependence of maximum amplitude of signal on the initial stage as well as in numerical experiment increases in linear and at a certain moment the speed of amplitude increase rises sharply which indicates the switch of the mechanisms of the generation of mechanical waves. Amplitude values of voltage graded by pressure with PZT (piezoelectric transducer) [6] coincide on the order of magnitude with the values obtained in numerical experiment 10 8 dyn/cm 2 .…”

“…Stress relaxation processes conditioned by metal fluidity occur at the initial stage of interaction, when maximal amplitude parameters have not been achieved yet, but ablation mechanism has not «switched on» yet. The same effect can be observed in nature experiments on treatment of titanium plates on accelerator TEMP-6 [6], which also has lengthy front of pulse increase of accelerating voltage and ion current. Identity of profiles of mechanical waves is observed when comparing the pulses measured experimentally (Fig.…”

“…A number of investigations are devoted to the questions of shock-wave excitement generation in metals under the HPIB influence [1][2][3][4][5][6]. In the range of intensities 10 7 …10 10 W/cm 2 in «HPIBmetal» system the thermoelastic and shot loading mechanisms occur simultaneously.…”

The system model «high power ion beam – metal» is suggested. Regularities of impulse formation of mechanical load in the volume of metal target subjected to the action of ion beams of different component composition in the range of power density 107...1010 W/cm2 have been considered. The influence of generation mechanisms on the profile and amplitude-to-time parameters of shock-wave excitation is studied.

“…Fig. 12 also shows the experimental data on pressure in a titanium target irradiated with a proton beam formed by a diode with an external magnetic insulation [23]. The authors studied a beam with the following parameters: the peak accelerating voltage of 350 kV, ion current density ranging from 200 A/cm 2 to 400 A/cm 2 and pulse duration of 150 ns.…”

This method can be used for the surface modification treatment of materials producing different surface properties. This paper presents the results obtained from an experimental work investigating the changes in some mechanical and microstructural surface properties of a 1.3343 steel (M2 high speed steel). In this work, a battery capacity of 800 µF, and four different sample plasma gun nozzle distances were used. The consumable electrode is tungsten in this work. The samples were subjected to micro-hardness measurements and it was found that the hardness values of modified surfaces are five-seven times higher than that of untreated samples. The modified surface layers were examined using an optical microscope and X-ray analyses were carried out for all samples. It was observed that surface treatment had led to the formation of new phases in surface layers. SEM and EDS analyses were applied to modified surface.
