| Abstract Scope |
Biodegradable magnesium alloys are promising materials for orthopedic implants due to their biocompatibility, biodegradability, and mechanical properties. Such properties enable superior performances compared to traditional permanent implants due to the reduction of stress shielding and secondary surgeries. However, their integration into clinical practice is limited due to rapid corrosion, prematurely compromising their mechanical integrity and practical use. Addressing this challenge requires the development of processing strategies and alloying approaches that simultaneously reduce degradation rates and maintain mechanical performance, paving the way for the successful development of biodegradable bone implants. Specifically, binary magnesium-calcium alloys present a compelling alternative, as calcium not only supports bone regeneration but offers the potential for controlled corrosion behavior. Through adopting various extrusion and processing pathways and assessing with property and microstructural characterization, we seek to identify which combination will yield the lowest corrosion and greatest mechanical properties. |
