提出的子项目的总体科学目标是描述高负荷摩擦系统中摩擦膜形成的摩擦和磨损机制，其中金属摩擦副的润滑是由塑料粘合的固体润滑剂实现的。具体地说，这种关系应该首先在简单的接触几何中进行检查和评估。在第二阶段，将一般结果转移到技术上证明的机器元件接触几何形状。特别注意的是固体润滑剂在塑料/金属相互作用中的提供和转移。其基础是以下工作目标：-在不同的操作条件下（表面压力、速度和温度以及反地形），表征固体润滑剂/金属接触中摩擦膜的形成，以及它对在不同的模型测试系统中进入和在高接触压力的金属/金属接触之间的传递过程的影响。-描述固体润滑剂成分、表面压力、速度、温度和摩擦膜形成之间的相互作用。-研究摩擦层形成的机制，并通过组件测试验证模型测试中获得的知识。-解释摩擦层形成的机制，并通过组件测试验证在模型测试中获得的知识。-比较不同摩擦系统中摩擦膜的传递和转移过程。-确定关系并制定可直接实施的应用结果。提议的项目涵盖了热塑性固体润滑剂在高机械应力摩擦学系统中的提供和传递过程的基本机理研究。一个成功的项目不仅可以更深入地了解摩擦膜形成的机制，而且可以使基于热塑性塑料的固体润滑剂系统用于工业应用。该项目涵盖了高表面压力下聚合物结合固体润滑剂摩擦学系统的输送和转移过程的基本机理研究。一个成功的项目，由于对摩擦膜形成机制的深刻理解，最终允许将概念转移到工业应用。

The overall scientific objective of the proposed subproject is to describe the mechanisms of friction and wear with respect to tribofilm formation in highly loaded tribological systems in which the lubrication of metal friction pairs is achieved by plastic-bonded solid lubricants. Specifically, the relationship should first be examined and evaluated in simple contact geometries. In a second stage, the general results are transferred to technically proven contact geometries in machine elements. Particular attention is paid to the provision and transfer of solid lubricant in the plastic / metal interaction. The basis for this are the following work objectives:- Characterization of tribofilm formation in solid lubricant / metal contact under different operating conditions (surface pressure, speed and temperature as well as counter topography) and its influence on the transfer process into and in between metal / metal contact with high contact pressure in different model test systems.- Description of the interaction of solid lubricant composition, surface pressure, speed, temperature and tribofilm formation. - Investigation of the mechanisms for tribolayer formation and validation of the knowledge gained in model testing by component testing. - Explaination of the mechanisms of tribolayer formation and validation of the knowledge gained in model testing using component testing.- Comparison of the delivery and transfer processes of tribo films in different tribosystems.- Identification of the relationships and formulation of directly implementable results for application.The proposed project covers the fundamental mechanistic investigation of the provision and transfer processes of thermoplastic-based solid lubricants in high mechanical stress tribological systems. A successful project can not only gain a deeper understanding of the mechanisms of tribofilm formation, but also enable a solid lubricant system based on thermoplastics for industrial application. The proposed project covers the fundamental mechanistic investigation of the delivery and transfer processes of polymer bonded solid lubricants tribological systems at high surface pressure. A successful project, due to a deep understanding of the mechanisms of tribofilm formation, ultimately allows the transfer of the concept to industrial application.
