Biodegradable stenting and implantation materials have received considerable attention in biomaterials community, with magnesium having been received most wide attention. However, magnesium corrodes too fast by nature, in human body environment. A new type of biodegradable metal – Fe and its alloys – has been introduced in recent years. In this study, a Fe 35 wt % Mn alloy was produced using powder sintering. Powder mixture was mechanically milled, pressed and then sintered to consolidate powder compacts. Microstructure characterization and hardness measurement were carried out on the as-sintered samples. In vitro degradability evaluation of the samples was performed in 5% NaCl and Simulated Body Fluid (SBF) media. The experimental results show that a higher porosity results in a higher degradation rate. All samples, with porosity being from 6.5% to 12.2 %, revealed a degradation rate from 0.6 to 1.4 mm/year.

Average Corrosion Rate

The influence of the addition element of Zn and Sr to degradation behavior of pure magnesium simulated body fluid (SBF) had been studied. The results indicate that the corrosion destroy on the surface of pure magnesium was reduced markedly through the addition element of Zn and Sr. The average corrosion rate of pure magnesium, Mg-1.0Zn and Mg-4.0Zn-1.0Sr alloy is 1.526 g/(m2•h), 1.337 g/(m2•h) and 1.163 g/(m2•h), respectively.

Micro Arc Oxidation

Bio-ceramic coatings were synthesized on ZK60 magnesium alloys by micro-arc oxidation (MAO). The degradation behavior of the ZK60 alloys with and without MAO coating in the simulated body fluid (SBF) was studied. The samples were characterized by means of scanning electron microscopy (SEM), laser scanning confocal microscopy (CLSM), and X-ray diffraction (XRD). Electrochemical impedance spectroscopy (EIS) was used to study the degradation behavior. The results showed that the porous MAO coating mainly consisted of MgO, Mg2SiO4, Mg3(PO4)2, and CaCO3. The pH values of both coated and uncoated samples increased over time. However, the pH values of the SBF for coated samples always maintained a lower level compared with those for the uncoated samples. Thereby, the coated samples showed a much lower degradation rate. After immersion in SBF for 5 days, corrosion product containing Ca and P was found on both samples, while the deposition was more active on the coated samples. The degradation models for the uncoated and coated samples in the SBF are also proposed and discussed.
