This project focuses on the fundamental description of mechanisms of metal toxicity and corrosion based on oxidative stress effects for new beta-Ti-alloys and Ti-based metallic glasses as well as the development of bacteria-killing oxide-based surface coatings and the analysis of their impact on those phenomena.
The tasks comprises the preparation of alloy samples by different casting techniques and their microstructural characterization, fundamental electrochemical studies and metal release analyses in simulated body fluids under ROS-forming conditions and accompanying surface analytical characterization. By means of anodization treatments nanoporous /nanotubular oxide coatings will be formed and doped with Cu, Ga or Ag; those coatings will be subjected to surface analytics. In collaboration with BIOREMIA partners in vitro biological studies are planned.
As a result, optimal bacteria-killing oxide-based surface states on new Ti-alloys with high corrosion resistance and limited oxidative stress effects will be identified.
The ESR will travel abroad for research secondments at different institutions of the BIOREMIA Network (e.g. at Univ. degli Studi di Torino- Italy; Univ. Autonoma de Barcelona- Spain; Stryker Trauma GmbH-Germany) and will participate in specialised training meetings and international conferences.
The ESR will enroll in the doctoral student programme at Technical University Dresden.
