摘    要:利用Al2(SO43分解, 在铝熔体中原位生成Al2O3颗粒。实验结果表明: 采用石墨坩埚、 电磁搅拌和铝熔体中加入镁的工艺流程, 可实现Al2O3颗粒和铝熔体的有效复合,进而制备出Al2O3p)/ZA35锌基复合材料; 与基体合金ZA35相比, 复合材料的耐磨减摩性能有了明显的提高。

Abstract: By means of decomposition of Al2(SO43, 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.
