Zusammenfassung:The formation of [Cr.sub.2][O.sub.3], Cr[O.sub.2], Cr[O.sub.3] and FeO, [Fe.sub.2][O.sub.3] oxides in surface layers of steel St3 samples irradiated with [Cr.sup.+] ions has been revealed. The oxide content decreases with increasing accelerating voltage, which is caused by a more intense surface sputtering and a temperature increase. It has been found that the hardness of a surface layer ~250 nm deep increases by 20% after irradiation with an accelerating voltage of 20 kV
