| Abstract Scope |
Magnesium (Mg) alloys are promising materials for temporary biomedical implants due to their strength, biocompatibility, and biodegradability. While prior studies have focused on improving corrosion resistance and mechanical properties, limited data exist on their performance under simultaneous mechanical loading and corrosion, as occurs in vivo. In this study, a custom corrosion chamber was developed to enable in situ mechanical testing under physiological temperature and pH. Braided Mg stents were tested in simulated body fluid under both static and cyclic compression. Cyclic tests at 10–20% compression across frequencies from 0.5 to 10 Hz assessed corrosion-fatigue behavior. Static tests at 10%, 20%, and 50% compression examined the effect of loading magnitude on corrosion and failure. Mechanical degradation and failure modes were correlated with the alloy microstructure. These findings provide insight into the performance of Mg-based devices under realistic service conditions and inform the design of next-generation bioresorbable implants. |
