【Abstract】 The applications of Intense Pulsed Ion Beams (IPIBs) to the surface modifications and coatings of materials have been recently investigated and demonstrated that this emerging technology, which is of flashheat effect for high energy density pulsed ion beam irradiation promises to be lowcost, highthroughout manufacturing. The irradiation effects of the intense pulsed ion beams with pulsed energy density of 106～109 W/cm2, pulse duration of <1 μs and their applications to the surface modification of materials are reviewed. The different kind of intense pulsed ion sources and their new developments for material science are also discussed. 更多还原
