AbstractBiodegradable Fe based alloys have been investigated for fracture fixation and cardiovascular support to overcome complications of permanent implants. This study was focused on the development of a new Fe-Mn-CCu alloy with antibacterial and anti-encrustation properties as a urinary implant material. The microstructure and mechanical properties of the alloy were studied. The degradation behavior, antibacterial and anti-encrustation properties were evaluated by immersion test, antibacterial test and encrustation test, respectively. The results showed that Fe-Mn-C-Cu alloy was a non-magnetic, biodegradable, anti-bacterial and anti-encrustation alloy that could inhibit the biofilm and stone formations on its surface through the dual effects of degradation and Cu ions release. The study revealed the preliminary mechanisms of anti-infection and anti-encrustation for Fe-Mn-C-Cu alloy due to the continuous release of Cu2+ ions, which provides a new idea for application of biodegradable Fe-based material and the treatment of urinary tract infections and stones in the urinary system.
