Abstract

Effect of irradiation with high power nanosecond pulse ion beams on physical and chemical properties of surface layers, fatigue strength and heat resistance of titanium alloys has been investigated. It was found formation of various shaped crater-like microdefects on the surface of these alloys under the action of ion beam pulses with high current density. The main disadvantages of up-to-date ion accelerators preventing their application on an industrial scale, such as a low uniformity of current density distribution throughout the beam cross section as well as insufficient beam parameters stability.
