Recently, an interest in biodegradable zinc based materials has been increasing. Pure zinc possesses low strength and corrosion rates. Magnesium, calcium and strontium appear as suitable alloying elements of zinc for application in implantology. It has been also found that the mechanical, corrosion and biological properties of various metallic materials can be influenced by microstructure modification. That can be reached by suitable thermal and thermomechanical treatment.
The aim of the proposed project is to design zinc alloys containing Mg, Ca and Sr and modify their microstructure by suitable thermal and thermomechanical treatment. Achieving of that aim needs an interdisciplinary approach, which is ensured by the high degree of the complementarity of the cooperating teams. The influence of various thermal and thermomechanical treatment on microstructure will be correlated with the evolution of mechanical, corrosion and biological properties of the prepared materials. Those will lead to better understanding of those relationships and help to broader use of zinc alloys in medicine.
