New Findings from University of Coimbra in the Area of Magnesium and Alloys Described (Design multifunctional Mg-Zr coatings regulating Mg alloy bioabsorption).

A recent study conducted by researchers at the University of Coimbra in Portugal explored the use of magnesium (Mg) alloys for temporary bone implants. While Mg alloys have favorable properties for biodegradability and compatibility with bone, their rapid degradation and inadequate strength limit their applicability. To address these issues, the researchers employed a surface coating technique using zirconium (Zr) to improve corrosion resistance, maintain biocompatibility, and enhance strength without compromising osseointegration. The study found that the Zr-doped coatings exhibited denser and refined structures with increasing Zr content, and demonstrated improved mechanical properties and corrosion resistance. These findings suggest the potential for using these coatings as functional biodegradable materials for temporary bone implants. [Extracted from the article]
