摘要：
In this study, hydroxyapatite and silver were added to Mg-1Zn-1Mn-0.3Zr alloy to fabricate ultrafine-grained metal matrix composites. Grain sizes of approximately 85nm were recorded by atomic force microscopy for the Mg-1Zn-1Mn-0.3Zr-5 wt-% HA-1 wt-% Ag composite. The contact angles in water and simulated body fluid on the ultrafine-grained Mg-1Zn-1Mn-0.3Zr-based composites were determined. Following a hydrofluoric acid treatment, the surface wettability changed from hydrophilicity to hydrophobicity. The electrochemical test showed that the corrosion resistance of the fluoride-treated specimens was higher, when compared with the untreated samples. The Mg-1Zn-1Mn-0.3Zr-5 wt-% HA and Mg-1Zn-1Mn-0.3Zr-5wt-% of HA-1 wt-% Ag composites modified with MgF2 have a higher degree of biocompatibility, which makes them potential candidates for medical applications
