TiC particles reinforced Fe matrix composites (TiCp/Fe) with different TiC volume fractions were prepared by in situ reaction synthesis process in conventional melting and casting route. The impact wear resistance and wear mechanism of the TiCp/Fe composites under casting and normalizing conditions were investigated using optical microscopy, SEM and a specially designed impact-abrasive wear device. Results showed that the impact wear of the TiCp/Fe composites occurred through microcutting, microploughing, and partly microcracking. With the increase of TiC volume fraction, the wear resistance of TiCp/Fe composites increased. The normalizing treatment greatly improved the impact wear resistance of the particle-reinforced composite due to formation of the fine secondary TiC particles.
