Migration of nitrogen implanted into iron induced by the presence of a buried carbon-rich layer

A redistribution of nitrogen atoms towards a buried carbon-rich layer is observed for thin iron films implanted at 250 °C. The effect is attributed to the formation of ε-Fe3−x(C,N) iron carbonitride. Above 300 °C the ε-carbonitride phase becomes unstable and consequently the redistribution effect va...

Description
Summary:A redistribution of nitrogen atoms towards a buried carbon-rich layer is observed for thin iron films implanted at 250 °C. The effect is attributed to the formation of ε-Fe3−x(C,N) iron carbonitride. Above 300 °C the ε-carbonitride phase becomes unstable and consequently the redistribution effect vanishes leading to well-separated profiles of nitrogen and carbon atoms.
