VTD Vakuumtechnik Dresden GmbH and Fraunhofer IWS Dresden are pleased to announce a new development: the DREVA 600-LAM PVD hard material coating plant.

An innovative system for depositing a new generation of DLC coatings on tools and components.
Jointly developed by Fraunhofer IWS Dresden and VTD Vakuumtechnik Dresden GmbH.

Diamor® carbon coating: ultra-hard, amorphous, free from hydrogen (Diamor® is the Trade name of Fraunhofer)

The new laser-arc module - the DREVA 600-LAM's key technological component - enables this Diamor® coating free from hydrogen.
With its new plant, VTD GmbH from Dresden consistently carries on the modular design of the DREVA series which is based on technological flexibility.
Six docking stations from the DREVA 600's basic system enable short-term conversions to and from arc coating or sputtering processes and combinations thereof as well as the integration of the laser arc module. This provides flexibility for an ideal coating in each individual application.

The DREVA 600-LAM has been developed to provide even greater competitiveness since the effort involved in manufacturing the product drops thanks to the ultra-hard, amorphous ta-C / DIAMOR®-carbon coating. Optimum tool coatings ensure a longer tool life and better cutting properties which in turn lead to a considerable reduction in costs.
The plant has a coating volume of up to 1,100 milling cutters with a shaft diameter of 6 mm and an unbeatably short process time of less than 180 minutes!
Extraordinary coating properties such as a hardness three times higher than that achieved with traditional DLC coatings as well as minimal friction values open up new horizons in the field of coating machining and shaping tools as well as bearing and sliding elements.
The coating process also makes an important contribution to protecting the environment since tools require fewer lubricants and sliding agents during use.
