Corrosion protection of magnesium alloys by electrophoretic deposition: Recent developments and future perspectives

In recent decades, there has been considerable interest in the production of biodegradable biomaterials derived from magnesium (Mg). Although Mg is prone to corrosion, its favorable properties—such as less density and excellent biocompatibility—have driven substantial research in this area. To enhance both the resistance to corrosion and biocompatibility, electrophoretic deposition (EPD) has been studied as an effective surface modification technique. This review offers a comprehensive examination of EPD coatings applied to alloys of Mg, incorporating various bioactive reinforcements. Additionally, it addresses the challenges faced by Mg-based alloys and explores potential directions for future research.
