Ge. Remnev et al., Ultradisperse powders obtained by sputtering a target with high-power nanosecond pulsed ion beam, TECH PHYS L, 26(12), 2000, pp. 1038-1040
We present the results of experiments on the obtaining of ultradisperse pow
ders by sputter ablation of aluminum and stainless steel targets bombarded
with high-power pulsed ion beams of nanosecond pulse duration. For an ion b
eam with an energy of 300 keV, a current density of 250-300 A/cm(2), and a
pulse width of 60 ns, the sputtered particles range in size from 2.5 to 700
nm and ale emitted within an angle of 30 degrees -40 degrees. A specific b
eam energy consumption for the powder production by sputtering an aluminum
target amounts to 6 (kW h)/kg. (C) 2000 MAIK "Nauka/Interperiodica".
