In this paper, TiC particle reinforced high chromium cast iron matrix composites were prepared in situ by casting and infiltration method. The effects of different volume fractions of moderator on the size of reinforced particles, volume fractions of reinforced particles, hardness of composites and abrasive wear were studied. The results show that the TiC particles become smaller and more uniform with the increase of the volume fraction of moderator, and the volume fraction of the enhanced particles also decreases with the increase of the volume fraction of moderator. The hardness of TiC increased by 69%. Abrasive wear tests show that the abrasive wear resistance of the composite with moderator content of 20% is the best, the lowest wear rate can reach 2.011E-008,and the wear resistance is 1.8 times higher than that of the metal matrix.
