dc.description.abstractTHIS WORK FOCUSES ON DEVELOPING NOVEL IRON-BASED SELF-LUBRICATING COMPOSITES REINFORCED WITH TI2SNC MAX PHASE PRODUCED BY POWDER METALLURGY. TWO AMOUNTS OF TI2SNC (5 AND 10 VOL%) AND THE ADDITION OF 10 VOL% GRAPHITE WERE EVALUATED. THE MICROSTRUCTURE REVEALED A PARTIAL REACTION BETWEEN THE MATRIX AND THE TI2SNC, EXHIBITING A DEGREE OF DISSOCIATION IN THE PRESENCE OF GRAPHITE, LEADING TO THE PRECIPITATION OF CARBIDES. THE ADDITION OF THE MAX PHASE SIGNIFICANTLY IMPROVED THE HARDNESS AND COMPRESSION STRENGTH. THE DRY COEFFICIENT OF FRICTION WAS AROUND 0.12 FOR FE + 5TI2SNC + 10GR, SHOWING A REMARKABLE REDUCTION IN WEAR RATE UP TO 85 % COMPARED TO PURE IRON. THE RESULTS DEMONSTRATE A SYNERGISTIC EFFECT BETWEEN THE MAX PHASE AND GRAPHITE, ENHANCING TRIBOLOGICAL PERFORMANCE AND WEAR RESISTANCE.
