Abstract Scope |
In the past decade, intensive investigations have taken place to develop temporary Zn-based implants. These materials possess an excellent combination of mechanical, corrosion and biological properties. Using conventional methods, including casting, extrusion, rolling or drawing, the final properties show only little improvement. The aim of this research is to develop new, bioabsorbable Zn-based alloys containing highly biocompatible Mg and antibacterial Ag, as well as Sr, using powder-metallurgy techniques, like mechanical alloying, spark-plasma sintering and powder-bed fusion. The additive manufacturing of Zn-based alloys needs careful fine-tuning of the process parameters due to the presence of volatile Zn. Detailed observations of the microstructures will be correlated with a variety of material properties, such as creep, fatigue and wear, which bring new knowledge about these relationships and enable the development of advanced bioabsorbable zinc alloys with tailored mechanical, corrosion and biological properties. |
