Abstract
ABSTRACT Mg-based bulk metallic glass (BMG) is a biodegradable metal with significant potential advantages as an implant material. To investigate the effect of Sr addition on the glass-forming ability (GFA) and its effect on the mechanical properties and corrosion behaviours of Mg–Zn–Ca–Cu BMG, a series of Mg66-x Zn29.5Ca4Cu0.5Sr x (x = 0, 0.3, 0.6, and 0.9 at.-%) were synthesised and investigated in this study. Microstructural characterisation, GFA and corrosion resistance measurements were carried out by XRD, DSC, SEM, immersion and electrochemical corrosion tests. The results showed that the addition of Sr improved the GFA and mechanical properties and enhanced and adjustable corrosion performance. In addition, the mechanical and corrosion property analyses showed that the Mg65.7Zn29.5Ca4Cu0.5Sr0.3 alloy exhibited the best mechanical properties and bio-corrosion resistance.
期刊介绍：
Corrosion Engineering, Science and Technology provides broad international coverage of research and practice in corrosion processes and corrosion control. Peer-reviewed contributions address all aspects of corrosion engineering and corrosion science; there is strong emphasis on effective design and materials selection to combat corrosion and the journal carries failure case studies to further knowledge in these areas.
