Abstract
Different experiments exist for the characterization of friction and wear in metal forming, which try to reproduce the tribological conditions of the forming process as precisely as possible. A particular challenge arises from processes such as cold extrusion, with contact stresses that are several times higher than the initial flow stress of the workpiece material. In this paper, a new experimental setup for wear testing is presented and compared with available tests concerning contact pressure, surface enlargement and sliding velocity. Using a special encapsulation of the specimen, the newly developed compression-torsion-wear-test is able to scale the contact pressure to a multiple of the initial flow stress of soft aluminium.
