“…Eventually, everything is defined by a problem specifics and the researcher ability to apply this or that method to the specific objective solution. The cascade and probabilistic method is one of options in theoretical methods numerous calculation for the spatial and power distributions of the falling and secondary particles in the environment [9][10][11]. From this point of view it's usage in scientific research is necessary.…”

Work is performed within a cascade and probabilistic method which essence consists in receiving and further usage of the cascade and probabilistic functions (CPF) for various particles. CPF make sense to probability that the particle generated at some depth of h' will reach a certain depth of h after n number of impacts. In work optimization calculation algorithms of the cascade and probabilistic functions (CPF) depending on interactions number and particles penetration depth is offered, concentration of radiation defects at ionic radiation for the purpose of reduction calculation time and quality. For calculation CPF and concentration radiation defects there is an area of result, border of this area and a calculation step. Borders and a calculation step selection automation is executed.

“…The windows of one door are hermetically closed with flanges (3). One flange of the other door is equipped with a quartz window 4 enabling a remote in-situ control of the temperature of the tool using pyrometer IMPAC IP 140 (LumaSense Technologies GmbH, Frankfurt am Main, Germany) and on the other flange are mounted two 180 mm wide and 200 mm high planar magnetrons (5). They form dual magnetron sputtering systems together with an AC 50 kHz power supply (not shown in Figure 1) connected between 140 × 160 mm 2 titanium targets of the magnetrons.…”

“…The useful life of tools, machine parts, and other products can be increased due to vacuum arc deposition [1][2][3][4][5] of wear-resistant TiN [6,7] and other coatings with a microhardness of~25 GPa, whose manifold exceeds hardness of the product material. The thickness of wear-resistant coatings synthesized on tools for rough cutting usually does not exceed 5-7 µm.…”

Y.A.M.); m.volosova@stankin.ru (M.A.V.)Abstract: A combined strengthening of cutting tools for finishing has been carried out in glow discharge plasma filling a process vacuum chamber. At the first stage, reamers rotating around the axis distanced from the magnetron targets at 8 cm were bombarded by fast argon atoms produced due to charge exchange collisions of ions accelerated in space charge sheathes between the plasma and a negatively biased to 3 kV grid with a 25 cm radius of its concave surface curvature. The reamer bombardment by fast neutral atoms led to a reduction of its cutting-edge radius from~7 µm to~2 µm. At the second stage, the reamer surface was nitrided within 1 h at a temperature of 500 • C stabilized by regulation of the negative bias voltage accelerating the nitrogen ions. At the third stage, a 3 µm thick TiN coating has been synthesized on the reamer bombarded by pulsed beams of 3 keV neutral atoms at a 50 Hz repetition rate of 50 µs wide pulses. After the combined strengthening, the cutting edge radius of the coated reamer amounted to~5 µm and the roughness of the area machined by the reamer holes in blanks made of structural steel reduced by about 1.5 times.
