Abstract
The accumulation of nitrogen to 14 at.% in the nanosized surface layers of samples of 03Х17Н12М2 stainless steel after implantation of N+ ions, the formation of metal nitrides, mainly CrN chromium nitride, and solid solution introduction has been established. It is shown that implantation of N+ ions using pretreatment by Ar+ and O+ ions leads to a decrease in the maximum nitrogen concentration by 2 or more times. It is assumed that this is due to segregation to the surface layers of iron atoms under irradiation by Ar+ ions and the formation of Cr2O3 chromium oxide and CrOOH chromium hydroxide under irradiation by O+ ions.
