AZ91D Magnesium alloy matrix composites (MMC) were fabricated by squeezing-infiltration casting with the preform made of crystallined aluminum silicate short fibers as reinforcement and aluminum phosphate as binder at high temperature. Drying sliding friction and wear resistance of the MMC were examined by means of MM200 wear tester ( block-on-ring configuration) against a hardened alloy steel counterface with 53HRC under loadings of 10 N,30 N and 50 N at 0.47 m/s and 0.92 m/s, and the wear morphology of the tested specimens was observed by scanning electronic microscope ( SEM ). The results indicate that wear mechanism of the MMC is characterized by abrasive wear with loadings 10 N and 30 N at 0.47m/s; while it is characterized by abrasive wear with slight flaking wear under loadings of 50 N at 0.47m/s, and it exhibits combined wear of abrasive wear with slight adhesive wear under loadings of 50 N at 0.94 m/s, increasing the wear resistance of the MMC.
