Abstract

Due to controlled and enhanced tribological conditions in forming technology, oils are generally used. Liquid lubricants, especially mineral oils, are environmentally harmful or even toxic. Within the priority program 1676, researchers are studying technologies to prevent the use of lubricants in forming operations. One approach to avoid lubricants in sheet metal forming is the generation of thin selective oxide layers (thickness of about 300–500 nm) on forming tools. In previous investigations, it was found that these layers (e.g. α-Fe2O3-layers) have the ability to reduce friction between the tool and sheet metal (DP600+Z) as well as zinc pick-up on the tool surface. Furthermore, the wear behavior of those layers was investigated. It could be shown that the oxide layer resists several thousand loads of stroke. Within this study, an overview of the previous work and the future activities of the task will be shown.
