Innovative bioabsorbable zinc-based materials for potential application as

cerebrovascular stents

Project is aimed at filling the highlighted gap, to explore the potentiality of PIII for Zn- based alloys, to study the relationship between the used parameters and the induced surface properties, from the point of view of resistance to corrosion, cytocompatibility and surface properties, and to make this knowledge available for the development of platform for plasma modification of alloys for biomedical applications.

The research will be conducted alongside two Polish partners the IMIM PAN (Institute of Metallurgy and Materials Science of the Polish Academy of Sciences) and the IWC PAN (Institute of High Pressure of the Polish Academy of Sciences) and in international cooperation with Université Laval (ULaval) in Canada. The investigations carried out at the IMIM PAN will consist of advanced microstructural characterization with some parts of corrosion studies. The IWC PAN will deal with the method of hydrostatic extrusion and mechanical tests. At ULaval plasma treatment by plasma immersion ion implantation (PIII) will be performed and surface analysis in order to determine the corrosion properties and biocompatibility of the investigated alloys. All institutions based on the obtained results will try to explain the mechanisms which control microstructure formation in deformed alloys, having a great impact on mechanical and corrosion properties.
