Composition of the research group

Efforts to use zinc-based orthopaedic and cardiovascular medical devices have intensified during the past decade. Such materials must possess an excellent combination of mechanical, corrosion and biological properties, which are closely related to the materials’ microstructures. Although various efforts have been made to improve the materials’ performance, conventional methods, including casting, extrusion, rolling or drawing, are normally considered.

The aim of the proposed project is the development of new, bioabsorbable zinc-based alloys containing highly biocompatible magnesium and antibacterial silver, using rarely favoured but newer and very personalized powder-metallurgy techniques, like mechanical alloying, spark plasma sintering, and selective laser sintering/melting.

Detailed observations of the microstructures will be correlated with a variety of material properties, including the generally overlooked 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. Those properties are also very important for better mimic of replaced or supportive medical applications in human body.
