Advanced surface texturing of hard coated cold forging tools

Project Status: finished


The surface topography of the workpiece and the tool plays a significant role on the tribological conditions in a forming process. Within this project the topography of cold forging tools, coated either by PVD or CVD, is to be textured by means of excimer laser radiation to improve its tribological behavior and to increase tool life. To increase tool life and decrease the amount of lubricant the micro textures have to be developed further by means of tribological basic experiments and industrial tool life tests. A model should be generated to predict the effect of micro textures and to adapt and apply micro textures to tools with different tribological and mechanical loads.
