Abstract Scope |
Biodegradable metallic materials are bioactive materials with a temporary support function, which then gradually degrade without a negative effect on the organism. Fe-based alloys possess excellent mechanical properties that can make them ideal candidates for applications where long-term support is needed. The main drawback of Fe-based alloys is their very slow degradation. Also, the very high Young’s modulus of elasticity can be a serious drawback, because human bone has higher value. Different approaches to achieving the appropriate biodegradability will be presented. The research is focused on Fe-Mn alloys, with the aim being to tailor the degradation rate using different approaches, such as chemical alloying, grain-boundary engineering and surface laser texturing, depending on the specific applications. The emerging additive-manufacturing (AM) technology makes it possible to advance the design and production of ideal, topologically porous metals that are suited to temporary implants. The AM process enables freedom of design to achieve bone-mimicking. |
