Degradation control of bioabsorbable magnesium alloys with anodized films

对于可生物吸收镁合金来说，根据受影响部位的情况控制腐蚀速度是至关重要的。然后，随着阳极氧化电压和电解液组成的不同，纯镁阳极氧化膜的形貌和成分也发生了变化。结果表明，在模拟体液中加入磷酸根离子可显著降低纯镁在模拟体液中的腐蚀速率。另一方面，腐蚀形貌取决于阳极氧化膜的孔洞形态。

It is crucial for bioabsorbable magnesium alloys to control the corrosion rate depending on the condition of affected parts. The morphology and composition of anodized films of pure magnesium was then varied with the anodizing voltage and composition of electrolytes. It was revealed that the corrosion rate of pure magnesium in a simulated body fluid noticeably decreased by the incorporation of phosphate ions in the anodized film. On the other hand, the corrosion morphology depended on the porous morphology of the anodized film.
