Increasing performance and lifetime of plastic / metal tribosystems by tribologically induced material conversion processes

在摩擦学系统中，塑料越来越多地被用作主体材料。除了聚合物基体外，一种现代的、摩擦学优化的、基于塑料的车身材料由增强部件和不同长度尺度的内部润滑剂组成。该项目的目的是研究在没有外部润滑的情况下，通过吸热反应与金属滑动伙伴100Cr6接触，显著提高塑料基杂化材料摩擦学性能的潜力。本研究的重点是对假设进行验证，验证后的效应一方面可以通过影响温度平衡和气固反应产物将基于塑料的摩擦学系统的载荷限制转移到更高的值，另一方面可以利用该系统的摩擦学可用性来保持较宽的载荷范围。该研究项目旨在通过实验、建模和仿真相结合的方法来探索所提出方法的可能性和局限性。

Plastics are used more and more as a body material in tribological systems. In addition to the polymer matrix, a modern, tribologically optimized, plastic-based body material consists of a reinforcing component and internal lubricants at different length scales. The projects aim is to investigate the potential of a significant increase in the tribological performance of plastic-based hybrid materials without external lubrication in contact with a metallic sliding partner of 100Cr6 by endothermic reactions. The study focusses on the verification of the hypothesis, after which the effect can be used on the one hand to shift the load limits for plastic-based tribological systems by influencing the temperature balance and gaseous and solid reaction products to higher values and on the other hand the tribological usability of such systems to maintain a wide load range.The research project aims to explore the possibilities and limitations of the proposed approach using a combination of experiment, modeling and simulation.
