Assessment of Galvanostatic Anodic Polarization to Accelerate the Corrosion of the Bioresorbable Magnesium Alloy WE43

In the field of surgery, bioresorbable magnesium is considered a promising candidate. Its low corrosion resistance, which disadvantageous for technical application, advantageous surgery since implant fully degrades in presence water-based body fluids, and after defined time regenerating bone takes over its function again. Therefore, knowledge behavior several months essential. For this reason, an vitro short-time testing method developed to accelerate progress by galvanostatic anodic polarization without influencing macroscopic morphology. The initial rate alloy WE43 calculated detection hydrogen volume produced immersion test. corresponding experimental setup, applied with three-electrode system. application range determined based on current density from potentiodynamic polarization. To correlate rate, accelerated dissolution morphologies both test strategies are characterized microscopy images, as well energy dispersive X-ray spectroscopy Fourier-transform infrared spectroscopy. results demonstrate that can be increased order decades limitation changed morphology increasing With approach, it possible characterize exclude new unsuitable alloys time-efficient manner before they used subsequent preclinical studies.
