A method is proposed for improving the performance properties of various materials, based on the synergy of high-intensity ion implantation and simultaneous energy impact on the surface, aimed at creating deep ionalloyed layers. Its implementation requires the use of repetitively-pulsed high-power density beams of metal and gas ions of submillisecond durations. This article presents the results of experimental studies on forming pulsed high-intensity titanium ion beams from vacuum arc plasma. The effect of the cell size of the grid electrode, shaped as a part of a sphere, on the focusing and transport efficiency is studied. A possibility of ballistic focusing of a titanium ion beam with a pulse duration from 150 to 500 μs and a power density of up to 100 kW/cm2 is experimentally shown.
