| Abstract Scope |
Magnesium alloys are emerging as promising candidates for temporary, wire-based implants due to their desirable combination of strength, biocompatibility, and biodegradability. This study investigates the corrosion-induced degradation of mechanical properties in two novel magnesium alloys, WE43MEO and ZX10. To assess their potential for applications such as stents, sternal cables, staples, and sutures, we investigate how corrosion affects the wires' mechanical properties. This involves analyzing changes in strength and ductility after exposure to a corrosive environment through quasi-static tensile testing and evaluating fatigue behavior under cyclic loading within the corrosive media. In addition, their initial microstructural features and susceptibility to pitting will be examined to understand its influence on the overall corrosion behavior and the resulting mechanical properties. The findings from this comparative study will contribute to the development of tailored biodegradable implants optimized for specific applications within the field of bioresorbable medical devices. |
