A Mössbauer study of plasma nitrided iron [PDF]
Journal of Applied Physics, 1998 Iron powder has been nitrided in a glow discharge plasma of a mixture of nitrogen and hydrogen, in order to verify the existence of a metastable iron nitrogen solid solution, previously observed from the Sm2Fe17N3 phase decomposition process. Our results show that, for short nitridation times, we obtain a mixture of Fe4N, a small amount of α-Fe and an ...

Tribocorrosion behaviour of plasma nitrided and plasma nitrided+oxidised Ti6Al4V alloy [PDF]
Surface and Coatings Technology, 2006 This paper reports the influence of low pressure plasma nitriding treatments, some of them followed by plasma assisted oxidation on the mechanical properties and tribocorrosion resistance of a Ti6Al4Valloy. Nitridation was performed for 640 or 720 min at 600 and 700 °C in a r.f. plasma equipment, using a N2–H2 gas mixture at 7.5 Pa. Some of the samples
