Corrosion Behavior of Gravity Cast and High-Pressure Die-Cast AM60 Mg Alloys with Ca and Y Addition

In this study, the microstructure and related corrosion behavior of AM60 alloys with/without Ca Y addition upon gravity casting (GC) high-pressure die-casting (HPDC) are investigated by means SEM/EDS characterization, immersion/salt spray test, hydrogen releasing, as well electrochemistry examination. When utilizing GC, alloy with (named AZXW6000 alloy) has better resistance compared alloy. Thanks to grain refinement second phase networks introduced in HPDC, anti-corrosion properties AM seem much than those GC counterpart. The mechanism both GCed HPDCed AM60-based is also detail. inspiration from present work can provide more thinking for developing high corrosion-resistant Mg using different methods.
