Influence of Alloying Agents on the Biodegradability of Zinc

In the present work, the in vitro biodegradation of Zn and its Zn-AlAl and Zn-Mg alloys with potential applications as biodegradable metallic materialsMaterials was studied. For this, electrochemical techniques were used: potentiodynamic polarization curves and electrochemical impedanceImpedance spectroscopy, EIS. Likewise, immersion tests were carried out over time. All experiments were carried out in a medium that simulates the body environment: phosphate-buffered saline with pH 7.4 and at a controlled temperatureTemperature of 37 ºC. It was found that the addition of alloys improves the behavior against Zn degradation in a solution that simulates the body environment. Therefore, the Zn-AlAl and Zn alloys studied are suitable candidates to be used as potential biodegradable metallic materialsMaterials.
