| Outline of Final Research Achievements |
In recent years, the application of bio-degradable materials for medical implants has drastically increased. Therefore, much research about magnesium-based stent applications has been focused on controlling the corrosion rate, mechanical properties, effect of magnesium alloy on our body so that the bio-corrosion of the stent applications can be tailored to the specific anatomical site. The corrosion behavior in the fluid flow was influenced by these environmental conditions such as the strain, the surface condition and the flow rate. Thus, our project in the present work is to evaluate the corrosion progress of the specimen geometries in the fluid flow field. The corrosion test of the various samples was carried out using the sodium chloride solution in a simulated blood fluid. Then, the mass loss, the corrosion behavior and the corroded area was evaluated. From the results of corrosion test, the corrosion behavior of AZ31 magnesium alloy in the flow field was clarified.
