Forschungsinstitut für Edelmetalle und Metallchemie (fem)

Since 1922, the Research Institute for Precious Metals and Metal Chemistry in Schwäbisch Gmünd is active as an independent and not-for-profit institute especially in the area of metal research and surface engineering. The focus lies in the application of different coating technologies like electroplating, anodization, finishing technologies and gas phase deposition technologies.  In the department Electrochemistry/Electroplating/corrosion the focus is mainly on the exploration and optimization of new layer materials, coating processes and the analysis and characterization of metallic coatings and composite systems. 2004, at fem the aprotic deposition from ILs was started as a research topic. Since then, the preparation of different layer systems was studied by Dr. Böck. Subject was e.g. the replacement of this Ni diffusion layers by iron layers deposited from IL [1]. Because of the high innovation potential this research topic forms a exploratory focus [2], like for deposition of Al layers [3, 4], for preparation of magnetic materials [5] and to widen the application range of noble metals. In the past years studies on the deposition of noble metals from ionic liquids have been carried out. It was possible to show that by application of the right current profile and use of an additive a significant improvement of deposition rate, current efficiency and layer quality can be reached  [6-9].
