Brief description

The aim of the project is to increase the energy and material efficiency of the combustion engine by means of novel, nanoscale structured, hard and self-lubricating carbon-based coatings. The focus of the work is on reducing friction and wear on tribocontacts. The consortium has already worked together very successfully on thin carbon-based functional coatings for selected engine parts and will now contribute this expertise to enable the use of these coating systems in biogenic lubricants and fuels and at higher temperatures in particular. The application-related optimization is carried out on purely carbon-based coatings ("diamond-like", highly tetragonally coordinated carbon, "ta-C") on the one hand, and on coatings that contain another structure-forming element, usually a transition metal (metal-doped, "C:TM"), on the other. These layers are usually produced by low-pressure processes such as magnetron sputtering, arc evaporation or plasma-assisted deposition from the gas phase. In recent years, new approaches have been developed for the further development of this class of materials, which describe particularly nanoscale structured systems. The aim of this interdisciplinary sub-project is to advance these developments along the chain from atomic understanding of structure and growth to use in conjunction with new materials, including those from other project areas, and to develop them for mechanical, plant and vehicle engineering in the overall project.
