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 properties 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 surface was analyzed using scanning electron microscope(SEM).
