Mechanically driving supersaturated Fe–Mg solid solution for bone implant: Preparation, solubility and degradation

Fe has attracted great attention as biodegradable bone implant. Unfortunately, its degradation rate is too slow for bone repair. It is well known that the lower the electrode potential is, the faster the metals degrade. In the case of dissolving low electrode potential species (Mg for instance) into Fe lattice, the corrosion potential of the matrix can be negatively shifted and the overall degradation rate can be accelerated. However, Fe and Mg...
