Surface functionalization of forming using direct laser interference patterning for dry forming applications

Forming processes typically require the use of lubricants to reduce friction and wear of the tools as well as to protect the semi-finished products. Since cleaning of forming products is costly and time-expensive, there is a need to eliminate the use of lubricants. An approach to improve the performance of tools in dry forming is by producing micro structured tools or even to structure the semi-finished products. This study presents an overview about the potential application of direct laser interference patterning for the functionalization of surfaces involved in dry metal forming processes.
