Herrera2, Gabor Szakács3*, Carla Vogt2* and Norbert Hort3* 1 University of Applied Sciences Stralsund, School of Mechnaical Engineering, Germany 2 Institute of Inorganic Chemistry, Leibniz University Hannover, Germany 3 Helmholtz-Zentrum Geesthacht, Magnesium Innovation Center, Germany Magnesium wires have recently gained interest in the area of biodegradable metallic materials for biomedical application: either for pins, rods and clips for temporary fixation of bone fracture with a wire diameter in an mm range or for forming stents with much smaller diameters around a few 100 µm or less as fine wires. In this research a warm drawn Mg6Ag wire of a diameter of 1.6 mm has been investigated. Due to recrystallization during or after their complex forming processes, this wire shows a fine grained microstructure resulting in high strength and ductility. Binary Mg-Ag alloys are designed as antibacterial material to treat infections in an implant site and it has been indicated that Mg-Ag alloys have satisfactory corrosion properties under cell culture condition and much better mechanical properties than pure Mg. Focus of this study is not the remaining strength after corrosion or the corrosion morphology, but the analysis of the corroded wires and the corrosion products changing as the function of exposure time. Analysis included qualitative and quantitative SEM imaging with EDX, XRD, Raman, μ-XRF and IR spectroscopy and ICP-OES. The Mg6Ag wire of this study corrodes under forming Mg(OH)2, CaCO3 and AgCl showing strong weight loss and pitting corrosion.
