Abstract

This study investigated the microstructural and corrosion resistance modifications in Mg–0.8% Si alloy with Sn addition. Sn effectively refined Mg₂Si morphology and distribution. Mg–8% Sn–0.8% Si consisted of α-Mg, Mg₂Si, and Mg₂Sn phases, with Mg₂Sn enriched at grain boundaries. Sn significantly enhanced corrosion resistance by 14–17 times, with limited improvement beyond 8% Sn. Mg₂Sn formation, SnO₂ layer, and fine Mg₂Si barrier contributed to improved corrosion resistance.

Sn对Mg-0.8% Si合金组织和腐蚀行为影响的研究

研究了添加锡对Mg-0.8% Si合金组织和耐蚀性的影响。锡有效地细化了Mg2Si的形貌和分布。Mg-8% Sn-0.8% Si由α-Mg、Mg2Si和Mg2Sn相组成，Mg2Sn在晶界富集。锡的耐蚀性提高了14 ~ 17倍，但超过8%后提高幅度有限。Mg2Sn的形成、SnO2层和良好的Mg2Si阻挡层有助于提高耐蚀性。
