Corrosion Behavior of P-Coated Biomedical Pure Magnesium

Abstract:

Magnesium and its alloys are potential materials in biodegradable hard tissue implants. However, the fast degradation rates in a physiological environment constitute the main limitation for biomedical application. In this work, the NH₄H₂PO₄- KMnO₄ chemical conversion treatment on the surface was used. The morphology and structure of the coating was observed and analyzed by SEM. The electrochemical behavior in Hanks' simulated body fluid of the coated magnesium was systematically investigated. Our results disclose that the corrosion resistance of the P-coated magnesium is significantly improved.
