The efficient use of resources are becoming more important due to economic and environmental requirements. In widely used forming processes like deep drawing an avoidance of lubricants – namely dry deep drawing – is a key factor for saving resources. In this paper, a combined approach consisting of a macro-structured tool design and a special modified protective coating is presented. The combination ensures a stable process with a sufficiently wide process window under dry conditions. The absence of lubricants in critical areas has to be compensated by tetrahedral amorphous carbon ta-C films which is additionally structured by Direct Laser Interference Patterning (DLIP) for further improvement of the tribological performance.
The German Research Foundation (DFG) is greatly acknowledged for financial support (Priority Programme 1676 “Dry Metal Forming - Sustainable Production through Dry Processing in Metal Forming” – SPP 1676). The authors would like to thank the Chair of Large Area Laser Based Surface Structuring for creating the coatings and the DLIP structures.
