Abstract: The TiC particle reinforced ZA-12 matrix composites was fabricated by XD^TM process combined with stirring casting and its friction and wear properties under dry conditions were investigated using MM-200 wear testing apparatus. The effects of TiC particle content and applied load on the wear resistance proper ties of the composites were studied. The results show that the friction and wear properties can be greatly improved with an increase in the TiC particle content . The wear mass loss of the composites and the unreinforced ZA-12 matrix alloy increase with increasing applied load, but the increased extent of the former is smaller than that of the latter. Finally the morphologies of worn surf ace was analyzed using scanning electron microscope(SEM).
