摘要：

The effect of high-dose, with a fluence > 10(18) cm(-2), irradiation with hydrogen, helium, and neon ions with energies from several hundred eV to 30 keV on the surface morphology of polyacrylonitrile (PAN) carbon fibers has been experimentally studied. Magnetron sputtering with ions of low, less than 1 keV, energies of carbon fibers leads to the formation of a whisker-like relief on the surface. Such relief at irradiation with 30 keV ions is formed at the initial stage of high dose irradiation at fluences of similar to 10(16) cm(-2). At higher fluences > 10(18) cm(-2) depending on the sort of ions, submicron longitudinal or transverse corrugations are formed. The obtained results are discussed within the framework of existing models of formation of ion-induced morphological elements on the surface of graphite-like materials.
