Controlling the solid-state reaction in Fe-MoS2 self-lubricating composites for optimized tribological properties

Gabriel Araujo de Lima, Aloisio Nelmo Klein & Kaline Pagnan Furlan
In this work, self-lubricating composites containing MoS2 and graphite dispersed in an iron matrix were produced by powder metallurgy and sintering. Previous studies demonstrate that MoS2 reacts with iron matrixes during sintering, making the production of Fe-MoS2 composites rather difficult. Therefore, this study focused on a potential solution to avoid or reduce this reaction, whilst still providing good tribological properties. Our results show that the addition of graphite retards the reaction of MoS2 with iron...
