Non-Ferrous Metals And Their Alloys

Our team has long-term experience in metallic materials designing and testing, especially titanium and its alloys, which is confirmed by the participation in many R&D projects, also international ones.

 The team’s main areas of research include the following aspects:

  • designing and characterisation of microstructure and properties of titanium alloys for biomedical applications by way of mechanical, thermo-mechanical processing and surface engineering methods,
  • large and severe plastic deformation processes and their ability to obtain nanomaterials and ultrafine-grained materials,
  • electrochemical tests of corrosion resistance of metallic materials,
  • characterisation of biomedical metals after corrosion and biological tests,
  • consolidation of metal chips with the use ofplastic processing,
  • characterisation of the microstructure and properties of multilayered laminates produced using the explosive cladding technology,
  • characterisation of the degradation processes of catalytic gauzes used in the ammonia oxidation process,
  • diagnostics of artworks and archaeological objects.

The group cooperates with both Polish and foreign research centres, such as: the Institute for Sustainable Technologies (Radom), the Institute of Physiology and Pathology of Hearing (Kajetany), Institute of Optoelectronics, Military University of
Technology (Warsaw), Friedrich–Alexander University Erlangen–Nürnberg (Germany), Chalmers University of Technology (Sweden), Karlsruhe NanoMicro Facility (Germany), Clemson-MUSC Bioengineering Program (USA).
