Abstract:
The formation of Cr$_2$O$_3$, CrO$_2$, CrO$_3$ and FeO, Fe$_2$O$_3$ oxides in surface layers of steel St3 samples irradiated with Cr$^+$ 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 $\sim$ 250 nm deep increases by 20% after irradiation with an accelerating voltage of 20 kV.
