Modification of Surface Layers by Irradiation with a Long-Pulse Intense Ion Beam

Abstract
The effects of irradiation produced by long-pulse, intense ion beams on metal surfaces (Al, stainless steel and Ti) and silicon surfaces were investigated. These beams were comprised of proton or carbon ions with pulse widths of ∼300 ns, current densities of \lesssim1 kA/cm2 and energies of ∼80 keV. The observed molten surface structures and recrystallized layers (20 µm depth) indicated that the surfaces reached high temperatures as a result of the irradiation. Changes in the X-ray diffraction patterns also indicated recrystallization by a rapid heating of the surfaces. Titanium carbide was produced by carbon-ion irradiation on a titanium surface; this process was verified by ESCA measurements.
