| Research Abstract |
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.
