The neotype magnesium alloy, Mg-Nd-Zn-Zr (NZK) alloy, was implanted into the rabbit femur to investigate its in vivo degradation behavior and biocompatibility. Seventy-two New Zealand white rabbits were randomly divided into the NZK alloy group, titanium alloy group and sham-operated group. Then NZK alloy rods were embedded in the rabbit femur in the NZK alloy group, titanium alloy rods were em...
BACKGROUND Degraded and osteogenic property of coated magnesium alloy was evaluated for the fracture fixation in rabbits. METHODS Magnesium alloy AZ31 with a different coating thickness by microarc oxidation was used, and the bilateral radial fracture model was created by the bite bone clamp. Thirty-six New Zealand white rabbits in weight of 2.5~3.0 kg were randomly divided into A, B, and C g...
The effects of Grp (graphite particles) addition and holding time on the microstructure mechanical properties Grp/AZ91D composite were investigated in this work. results indicated that distribution matrix was determined by self-stabilizing mechanism relationships between solidifying interface particles. Due to mechanism, a small amount would uniformly distribute melt alloy, as increased, agglom...
The biodegradable ability of magnesium alloys is an attractive feature for tracheal stents since they can be absorbed by the body through gradual degradation after healing of the airway structure, which can reduce the risk of inflammation caused by long-term implantation and prevent the repetitive surgery for removal of existing stent. In this study, the effects of bicarbonate ion (HCO₃-) and m...
