For lightweight construction the use of high-strength aluminium alloys plays an increasing role. Hence, in forming processes tools are subject to severe stress. Especially abrasive wear and adhesive properties require the application of lubricants and separators. Due to environmental compatibility and enhanced energy efficiency a minimum of additives is wanted. For this reason the tribological system between tool and workpiece has to be influenced by appropriate surface treatment or coating techniques. For design of forming tools, surface properties and the resulting loading conditions have to be adapted. Appropriate coatings are selected and guidelines for the design of the forming tools are worked out by using numerical simulations.
