It was found that irradiation with Ar + ions of 03X17H12M2T stainless steel leads to segregation of iron atoms to the surface, and when irradiated with O + ions in the nanoscale surface layers of the steel under study, oxygen accumulates, which is accompanied by the formation of chromium oxide Cr2O3.
