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

The 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. These methods offer a wide range of possibilities for the modification of deposition parameters and for the coating of various materials (steels, hard metals, metals, plastics, ceramics, glass, textiles). Substrates and components can be coated stationary, with single or double rotation as well as roll-to-roll (R2R). Applications range from wear and corrosion protection to decorative applications, biocompatible coatings and energy technology (fuel cells). PDF Download

Current Research Projects

The transfer of knowledge from research to industrial practice is all the more successful the earlier we cooperate with SMEs and large companies in our R&D work. This is why we are always on the lookout for companies to join the Project Support Committees (PA) of our new and ongoing IGF projects. If you are interested, please contact the respective contact person directly or use the contact form.
