Corrosion Performance of Additive Manufactured Zn as Biomedical Implants

摘要

Zn alloys are promising biodegradable materials, and additive manufacturing (AM) is a novel fabrication technique. However, AM Zn often experiences structura l changes compared to traditionally cast samples, which can subsequently affect their corrosion behavior. This study reviews the AM technologies for biodegradable Zn alloys and summarizes the corrosion-affecting factors from both AM and sample sides. Furthermore, this study summarizes the corrosion behavior of AM-ed Zn and Zn alloys through the comparison with the cast counterparts, aiming to analyze the impact of AM on the corrosion behavior of Zn alloys, and providing a theoretical foundation and technical support for the application of biodegradable Zn alloys.
