Abstract
Specimens of alloy steel containing 12% chromium as a major alloying constituent were implanted with 100 keV N2+ ions at a constant fluence of 1 × 1017 N2+ cm−2. The estimated specimen temperature during implantation did not exceed 450 K. Two kinds of specimens were used for implantation: electropolished and mechanically polished. Iron nitrides of the Fe16N2 type and mixed iron chromium nitrides (Cr,Fe)2Ni1−x (x = 0–0.5) were found in electropolished samples. In mechanically polished samples the Fe16N2 nitrides predominated. The influence of markedly different surface layers on nitride formation and their detection by diffraction methods is discussed.
