The corrosion properties of ternary (Ca65Mg15Zn20 and Ca50Mg20Cu30), quaternary (Ca55Mg18Zn11Cu16), and quinternary (Ca55Mg15Al10Zn15Cu5) amorphous alloys were evaluated using static aqueous submersion at room temperature. Ca-Mg-Zn and Ca-Mg-Cu alloy systems experienced destructive corrosion reactions. Ca-Mg-Zn-Cu and Ca-Mg-Zn-Cu-Al based amorphous alloys demonstrated positive corrosion properties, forming corrosion films up to 23 μm thick in the quaternary alloy and 11 μm thick in the quinternary composition. Corrosion products were evaluated using X-ray diffraction (XRD), X-ray Fluorescence (XRF), Scanning Electron Microscopy (SEM), and Energy Dispersive Spectroscopy (EDS).
