Independent Investigation of the Contact Normal Stress and the Surface Enlargement with the Sliding Compression Test.
In: Proceedings of the 16th International Conference on Advances in Materials and Processing Technologies, Taipei, Taiwan, 9/2013, [Conference or Workshop Item]

Abstract

Cold forging is a highly efficient process to produce components. However, the occurring tribological loads are tremendous. Therefore, complex tribological systems are necessary. They can be influenced by numerous factors. Most important are the tribological loads, which can usually be investigated independently. On the other hand, the contact normal stress and the surface enlargement are coupled in tribometer tests. In order to investigate them independently, a new concept for the Sliding Compression Test is presented and verified. This procedure reveals that both values have an influence on the friction coefficient. However, the influence of the surface enlargement is with about two-thirds higher.
