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 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...

The hydrolysis of Mg-based materials appears to be an ideal solution for clean energy production. Green hydrogen was produced by the reaction a “standard” AZ91 alloy (called in following) “model” seawater solution. Two milling speeds (i.e. 250 rpm and 350 rpm) were tested enhance reactivity AZ91. Graphite AlCl3 used as ball additives. Milling at higher rotational speed is more energetic, hence ...
