Coating of components

We coat 3-dimensional objects made of metal, ceramics, or glass in order to adapt their surface properties and so improve their functionality and service life. Using vacuum coating technologies such as sputtering technology, plasma-activated high-rate deposition, and high-rate PECVD, we improve the resistance of tools and components to corrosion, scratching, and abrasion. Decorative features, demanding optical properties, biofunctionality, and biocompatibility can also be achieved by applying suitable layers and multilayer systems.

Physical and material characterization studies and biocompatibility tests in our biomedical laboratory unit enables  us to directly test the effects of coatings and provide our customers with effective solutions for modifying their materials and products. Our range of services thus covers feasibility studies and small series right through to technology transfer to full production of processes/products developed at the Fraunhofer FEP.
