Abstract
A magnesium alloy containing Ca, Ti, Zn, and In was synthesized via high-energy ball milling of elemental powders followed by spark plasma sintering. X-ray diffraction and scanning electron microscopy revealed a homogeneous matrix with dispersed Mg-rich phases and intermetallics. Potentiodynamic polarization tests revealed low corrosion current density (9.6 f 2.1 mu A/cm2), a noble corrosion potential (-1197 f 4 mVSCE), and a clear passive region, indicating excellent corrosion resistance. Nanoindentation tests showed high hardness (2.61 f 0.21 GPa) and elastic modulus (55.35 f 5.47 GPa), exceeding those of commercial Mg alloys.
