Corrosion performance of melt-spun Mg67Zn28Ca5 metallic glass in artificial sweat

The Mg-based metallic glass developed in this study provides an alternative for Mg alloys for being used in daily life. In this study, the corrosion behaviors of melt-spun MgZnCa ribbons with and without heat treatment were investigated in artificial sweat. Surface morphology analysis showed that am...
