Our group develops unique methods of surface modification of materials, including multi-component and composite surface layers with a nanocrystalline structure. Excellent functional properties of the produced layers have already gained national and international recognition, confirmed by applications in medicine and industry.

The developed methods of producing surface layers mainly use non-equilibrium plasma, new reactive gas atmospheres containing environmentally safe organic compounds, also in hybrid technologies. These technologies are realized by combining various surface treatment methods, such as: PDT, PVD, CVD and electrochemical processes. Thus produced surface layers are the most modern generation of anti-abrasive and anti-corrosion layers, which also enable the increase of mechanical properties of the treated construction and functional materials, such as: various grades of steel, titanium and its alloys, nickel and magnesium alloys, aluminum, polymers and polymers composites. The Group also does basic research in the field of mechanisms of layers formation in low-temperature plasma conditions. The research also concerns detailed characteristics of the produced surface layers in terms of microstructure, surface topography, chemical and phase composition, residual stresses in produced layers and mechanical, chemical and biological properties of the treated metals and polymer composites in terms of industrial applications and development of new construction solutions for devices for the implementation of the above mentioned processes
