Abstract Scope |
Biodegradable metals are bioactive materials with controlled temporary support function, that gradually degrade without a negative effect on the organism. They are suitable in specific areas of pediatrics, orthopedics and cardiovascular surgery. The properties of these materials are changed by combination of metallurgical, chemical and surface treatments. In Fe based alloys Mn is added in order to achieve the higher degradation rates and is the most appropriate alloying element for microstructural, corrosion, magnetic and toxicological properties.
The goals of the current research are the synthesis of new Fe-Mn alloys. We tried to influence the formation of certain grain boundaries with the appropriate thermomechanical processes, chemical alloying thus enabling the precipitation of phases along the grain boundaries, simultaneously with the segregation of surface-active elements that will further increase corrosion rate. In addition to this approach, we are investigating changes of the surface with laser-texturing, thus accelerating the degradation of the material. |
