Biodegradable Magnesium–Fluorapatite Metal Matrix Nanocomposite with Improved Corrosion Resistance for Biomedical Applications

The aim of this work was to prepare and characterize of biodegradable magnesium–fluorapatite metal matrix nanocomposite. Novel AZ91–FA nanocomposite were produced by AZ91 magnesium alloy powders and FA nanoparticles. Bio–corrosion behavior of the prepared AZ91–FA nanocomposite, and also the AZ91 magnesium alloy as control sample, were evaluated. The results showed that the presence of the AZ91–FA nanocomposite presented increased corrosion resistance compared to the AZ91 magnesium alloy. The addition of fluorapatite nano particles reinforcements to magnesium alloys accelerate the formation of an apatite layer on the surface, which provides improved protection for the AZ91 matrix
