Since bioresorbable implants are highly interesting for biomedical applications to reduce patient burden, significant efforts are ongoing to develop adjusted metal alloys. Apart from magnesium (Mg) alloys, the iron-manganese (FeMn) system is promising concerning its biocompatibility. Although Mn increases the degradation of Fe, further efforts are necessary to enhance the degradation rate. For example, silver (Ag) phases promote the cathodic dissolution of the matrix material due to their high electrochemical potential. Therefore, the development of new Ag alloys with an adapted degradation profile, are a focal point of this work. Due to the immiscibility of Fe and Ag, it is not possible to cast FeMnAgX alloys, but it is feasible to manufacture these alloys using powder-bed-based additive technologies.
