Abstract: TiCp/ZA-12 composites were fabricated by exothermic disposition method process and stirring-casting techniques. The microstructure and wear-resistant properties were investigated . The results show that TiC particles are formed in-situ and distributed uniformly in matrix. No particles aggregation and macro or micro precipitation are observed. The wear-resistant properties of composites increase with the increase of TiCp content, but will not increase when the TiCp content reaches constant value. Finally, the friction and wear mechanism were also discussed.
