The Department of Thin Films and Surfaces is a research unit within the Jožef Stefan Institute. Our main research activity is the development of hard coatings for the protection of tools and machine parts against wear. We are also engaged in the research on other fields of physics and chemistry of thin films, surfaces, plasma physics and vacuum technique. In our laboratories there are several analytical instruments for the characterization of thin films.

Within the department there is the Hard Coatings Center, where we deposit the coatings on tools for our industrial partners. On different coating machines we offer the deposition of various ceramic PVD hard coatings: TiN, CrN, TiAlN, AlTiN, TiAlSiN and aCN, as well as others upon special request.
