In-situ TiCp / ZA4 3 composites were prepared by the contact reaction method. The mechanical properties of TiCp / ZA4 3 composites and the friction and wear properties of the composites were studied. The experimental results show that TiCp / ZA4 3 composites have good mechanical properties at room temperature and high temperature (150 ~ 250 ℃), and the wear resistance of TiCp / ZA4 3 composites increases with the increase of TiC particles content.
