  • ABSTRACT: SiC- based composites containing a volume fraction of MoSi2, produced by metallurgy processes, display good mechanical properties, high sinterability and machinability and, consequently, are promised candidates as materials for high temperature. For many industrial applications, the wear resistance of these composites is of paramount importance in the in-service life duration. In the present work the resistance to abrasive wear of SiC-MoSi2 composites containing different volume fractions of MoSi2 (0, 10, 20, 30, 75, 100%) was investigated by means of micro-scale abrasion tests (MSATs), carried out in order to evaluate the influence of phase composition microstructures in the wear behaviour. The experimental conditions 8applied load, relative speed and concentration of abrasive slurry) were selected in order to allow a three-body rolling wear mechanism to be established. The morphology of worn craters was studied by optical and SEm microscopy. The effects of phase composition (literal)
