Article Preview

This paper deals with the influence of fourth element addition to the high strength Mg-Zn-Y extruded alloys with long period stacking ordered (LPSO) phase on corrosion resistance and surface film formation. Salt water immersion test, SEM observation, and EDX analysis are performed on Mg97Zn1Y2(at.%), Mg97Zn1Y1.9La0.1 and Mg97Zn1Y1.9Al0.1 alloys. The Al or La addition to the extruded Mg97Zn1Y2 alloy is effective for the formation of thin, dense and uniform surface layer, resulting in improvement of corrosion resistance.
