摘要

采用粉末冶金热压烧结方法

制备了SiCp增强的的预合金化6061Al复合材料。通过金相显微镜、扫描电镜、显微硬度、拉伸性能测试及电化学测试等方法

研究了SiCp含量对SiCp/6061Al复合材料的烘烤强化效应及腐蚀性能的影响。结果表明

SiCp含量明显影响了SiCp/6061Al复合材料的烘烤强化效应及腐蚀性能。随着SiCp含量增加

复合材料的烘烤强化效应明显提高。当SiCp含量达到20%时

复合材料的抗拉强度提高较为明显

但伸长率却随着SiCp含量的增加而显著降低

同时SiCp的加入也降低了复合材料的耐腐蚀性能。

Abstract

SiCpreinforced pre-alloyed 6061 Al composites were prepared by powder metallurgy and hotpressing sintering.Effects of SiCpcontent on baking hardening and corrosion properties of the SiCp/6061 Al composites were investigated using optical microscope

scanning electron microscope

Vicker hardness

tensile testing and electrochemical test.The results show that the baking hardening and corrosion resistance of the SiCp/6061 Al composites are related closely with the volume fraction of SiC particles.When the volume fraction of SiC particles is 20%

the tensile strength of SiCp/6061 Al composite is improved obviously

while the elongation and corrosion resistance are decreased.
