Coatings play a considerable role in increasing the functionality of components. High-performance applied layers protect components from premature mechanical wear and tear, chemical and thermal degradation or minimize frictional losses in dynamic systems. Under operating conditions, coated 3D parts are exposed to extreme stress since the effects are maximized at higher temperatures and pressures, or components must bear the same loads at reduced weight. Component and coating must therefore be matched to each other.
NOVELLA, an experimental platform jointly developed by Fraunhofer FEP and CREAVAC GmbH, offers efficient high-rate electron beam deposition of 3D components. The facility permits pre-treatment, plasma-activated evaporation as well as hybrid processes in which electron beam technology can be combined with magnetron sputtering and plasma-activated chemical vapor deposition.
Important results for developing the design of NOVELLA experimental platform were incorporated from the collaborative project 3DEB funded by the European Union and the Free State of Saxony (grant agreement no 100146071).
