Abstract: By means of decomposition of Al2（SO4）3, Al2O3 particles were formed in situ in Al melt. The results show that by using graphite crucible and the method of electromagnetic stirring and adding Mg into Al melt, the combination between Al2O3 particles and Al melt is performed effectively. Basing that, Al2O3（p）/ZA35 zinc based composites was fabricated. The friction coefficient and wear resistance of Al2O3(p) /AZ35 zinc based composites were proved to be superior to those of matrix alloy ZA35 obviously.
