由于生态限制或技术上增加的工艺负荷，对金属成形摩擦学系统性能的要求越来越高，需要开发创新的摩擦学系统，特别是在不锈钢成形方面。初步工作表明，与地面参考表面相比，通过增量成形工艺机器锤击制造的深冲工具上的表面结构具有将带材拉拔试验中的摩擦降低约58%的潜力。这是由润滑剂袋的效果和在相互作用区域中减小的真实接触面积来解释的。然而，由于接触面积减小的影响，这些表面结构的耐磨性是它们在深冲压中应用的有效性的主要关注点。因此，在这项工作中，进行至少500次重复的带材拉拔试验，以评估摩擦特性。此外，研究了表面结构的涂层以提高结构的耐磨性。
Increasing demands concerning the performance of tribological systems for metal forming due to ecological restrictions or technologically increased process loads require the development of innovative tribological systems, especially in forming of stainless steel. It could be shown in preliminary work that surface structures on deep drawing tools manufactured by the incremental forming process machine hammer peening have the potential to reduce friction in strip drawing test by about 58 % in comparison with a ground reference surface. This is explained by the effect of lubricant pockets and a reduced true contact area in the interacting zone. However, due to the effect of a reduced contact area, the wear resistance of these surface structures is of main concern for the effectiveness of their application in deep drawing. Therefore, in this work strip drawing tests are performed over a minimum of 500 repetitions for the evaluation of friction characteristics. Additionally, the coating of the surface structures is investigated to improve the wear resistance of the structures.
