Previous studies have shown that MoS2 reacts with iron matrices during sintering, making the production of Fe-MoS2 composites challenging. We hereby demonstrate that a modification in the sintering atmosphere improves the composites' tribological properties due to a synergic effect of retardation of the solid-state reaction and increase of the matrix microhardness related to the nitrogen intake. The composites sintered in a mixed Ar/H2/N2 atmosphere exhibited, on average, a lower dry coefficient of friction compared to those sintered in Ar/H2.en1880-9014Funtai-oyobi-funmatsu-yakin = Journal of the Japan Society of Powder and Powder Metallurgy2025S47S53Kyōkaimolybdenum disulfide | self-lubricating composites | sintering | solid lubricantsTechnology::600: TechnologyImprovement of the tribological properties of iron-based self-lubricating composites by modification of the sintering atmosphereJournal Article10.2497/jjspm.14A-T2-09Journal Article
