摘要

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.
