摘要: Abstract The trend in modern materials science is the development of composite and coatings with a combination mechanical properties that provide higher strength reliability machine parts tools. deposition can be performed using plasma technology, such as enrichment metal surface alloying elements subsequent nitriding. In this work pulse glow discharge was used to enrich superficial layer molybdenum (Mo) then nitriding treatment conducted at high nitrogen concentration for compound layer. present study involves an analysis formed on powder metallurgy (PM) parts, sintered simultaneous then, nitrided. Both treatments were assisted by technology. particular, whether element Mo incorporated (dissolved) into iron nitrides investigated. different microstructures Mo-enriched after have been investigated employing light; scanning transmission electron microscopy (SEM TEM); X-ray diffraction (XRD); hardness measurements. Analysis entire enriched samples demonstrated γ-Mo2N fine precipitates
