Abstract Scope |
From economic and ecological points of view, the avoidance of lubricant usage in metal forming is desirable. The key challenge however is to influence the workpiece-tool interaction to be able to avoid friction and wear under dry metal forming conditions.
This contribution will give an overview the various approaches taken within the Dry Metal Forming Priority Programme that was launched in Germany back in 2013 and review a selection of the outcome after 6 years of research that involved a total of 25 research partners within 13 research projects. Approaches include coatings like diamond and DLC or self-regenerating coatings, macro- and micro-structuring of tool and workpiece surfaces, as well as application of volatile lubricants and electric currents.
As one example highlighted in more detail, an MMC deep drawing tool surface will be presented that is produced by laser melt injection of hard particles followed by subsequent laser ablation. |
