Resumen:
In the present work, the in vitro biodegradation of Zn and its Zn-Al and Zn-Mg alloys with potential applications as biodegradable metallic materials was studied. For this, electrochemical techniques were used: potentiodynamic polarization curves and electrochemical impedance 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 temperature 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-Al and Zn alloys studied are suitable candidates to be used as potential biodegradable metallic materials.
