The use of high-strength aluminum components in automotive manufacturing offers the opportunity to reduce vehicle weight significantly, in order to generate new lightweight potentials. In the past, the so-called hot forming and quench process (HFQ®) successfully demonstrated the potential for the production of complex-shaped components made out of age hardenable high-strength aluminum alloys. Currently, no method enables quench forming processes without the use of lubricants. To fulfill the increasing ecological and economic requirements, it is necessary to identify wear-reducing techniques to promote this forming technology in the future even more. This contribution investigates the interaction of lubricant and tool coatings on the tribological performance during quench forming of the high-strength aluminum alloy AA7075 at elevated temperatures. The aim of this contribution is the development of low-lubricant or lubricant-free forming strategies, designed for these components. For this purpose, the tribological behavior is investigated using both, flat strip drawing tests and deep-drawing operations. Subsequently, the component quality and wear behavior is compared, cause-effect relations are identified and subsequently discussed.
