This R&D track will develop coatings for increasing the productivity of tools for machining in composite materials. The developed coatings will be of the TiB2-type and based on a combination of DC sputtering combined with cosputtering involving High Power Impulse Magnetron Sputtering (HiPIMS). By combining DC and HiPIMS, a high deposition rate will be ensured while still achieving the unique benefit known from HiPIMS, i.e. better film adhesion, higher hardness, more smooth coatings, better edge coverage and different nano/micro structures. It is expected that the tool life and performance can be increased by at least a factor of 2 as compared with traditional coating systems such as e.g. TiAlN.

For tool and machine-components, the R&D work will also involve DC/HiPIMS development of metal-doped diamond-like-carbon DLC creating a harder DLC characterized by a higher temperature stability as well as improved friction properties.
