Corrosion behavior and biocompatibility of MgZnP@PDA coatings on biodegradable Zn 2Cu alloy

Key Points

• Corrosion behavior was significantly improved, demonstrating a reduction in degradation rate by approximately 30%.
• The MgZnP@PDA coating exhibited high biocompatibility scores, with cell viability exceeding 90% in vitro.
• Assessment using coating technologies highlighted the advantages of MgZnP modifications in preventing corrosion.
• These findings may enable better performance of biodegradable alloys in medical devices, though further studies are needed.
