Abstract

The paper presents results on dynamical processes caused by a high power ion beam (of E_average {reversed tilde equals} 0.45 MeV energy, j = (30 to 250) A/cm² current density and τ = 10 ^-7 s duration) interacting with surfaces of Cu, Al, Pb metals. Mass of the layer evaporated and deposited from metal surfaces was measured for various irradiation regimes. It has been shown that dynamical processes resulting from HPIB-metal surface interaction are related to changes in the metal structure at large depths which in turn cause changes in microhardness and abrasive wear resistance.
