dc.description.abstractFE-BASED SELF-LUBRICATING COMPOSITES, IN WHICH SIC PARTICLES ACT AS PRECURSORS TO IN SITU GENERATED 2D TURBOSTRATIC GRAPHITE AS A LUBRICATING PHASE, WERE PRODUCED VIA POWDER INJECTION MOULDING (PIM). IN ORDER TO STUDY THE PRECURSOR INFLUENCE ON THE SOLID LUBRICANT STRUCTURE AND PROPERTIES, HEXAGONAL (?) AND CUBIC (?) SIC POLYTYPES WERE USED. THE COMPOSITES WERE TRIBOLOGICALLY TESTED IN DRY AND LOW-VISCOSITY OIL-LUBRICATED CONDITIONS. DISTINCT PRECURSORS DID NOT LEAD TO SIGNIFICANT DIFFERENCES BETWEEN COMPOSITES. HOWEVER, DUE TO THE HIGHLY DISORDERED GRAPHITE-RICH TRIBOLAYER FORMATION, THEY DO PROVIDE LUBRICITY, LOW FRICTION COEFFICIENT, AND HIGH WEAR RESISTANCE, EVEN IN OIL-LUBRICATED CONDITIONS.
