Plasma Surface Technology · Materials Physics

We develop new layer systems for decorative and functional applications and examine physical and chemical material properties

The Plasma Surface Technology and Materials Physics department is engaged in vacuum-based depositions, in surface modifications and the characterization of materials with respect to the physical and chemical properties. The thin film deposition and surface modification is carried out using PVD (Physical Vapor Deposition) and PACVD (Plasma-Assisted Chemical Vapor Deposition) processes. The laboratory plants are equipped for magnetron sputtering (HIPIMS/HPPMS, MF, DC), cathodic arc evaporation, plasma beam deposition and pulsed CVD. Coatings were also prepared from a plastic varnish with different additives (e.g. nanoparticles). These methods provide a wide spectrum of possibilities for the modification of deposition parameters and allow the deposition of different materials like steel, hard metals, metals, plastics, ceramics and glass. The applications range from wear- and corrosion protection over decorative applications to magnetic storage media, sensors and catalysis.
