利用发射光谱和俄歇电子能谱研究了fer、FeNi和NiCr合金在辉光放电等离子体中的氮化过程。两种技术都提供了深度组成变化，此外，俄歇氮-金属原子间跃迁提供了有关N原子周围化学环境的信息。从氮- kll俄歇线形状和深度剖面的变化可以观察到氮化层中铬的富集。含铬合金中与N有较强亲和力的合金铬对层内化学成分的影响较大。
For FeCr, FeNi and NiCr alloys, iron nitriding in a glow discharge plasma was investigated by optical emission spectroscopy and Auger electron spectroscopy. The composition change in depth was provided by both techniques and, in addition, Auger nitrogen-metal interatomic transitions give information about chemical environments surrounding N atoms. Chromium-enrichment in the nitrided layers was observed from the variation both in the nitrogen-KLL Auger lineshapes and in the depth profiles. The chemical composition in the layers was strongly affected by the alloyed chromium having a strong affinity with N in the chromium-containing alloys.
