Coordination proposal for the priority program "Fluid-free lubrication systems with high mechanical load".

技术应用中的绝大多数摩擦学系统都是用流体润滑的，这些流体主要是油和润滑脂。例如，如果润滑剂在真空中蒸发，无法使用油或油脂进行润滑，则通常会在部件表面涂敷固体作为替代。固体层中的润滑机理与以流体作为润滑剂的摩擦系统有着根本的不同。研究课题的复杂性需要跨学科的方法，其中机械工程和材料技术的方法以及物理和化学模拟和分析方法必须以特定的网络方式使用。科学目标在优先计划“高机械负载的无流体润滑系统”中，研究了在固体润滑剂润滑下，在高机械载荷的摩擦系统中由于形成转移层而引起的摩擦和磨损机理。在第一个供资期，重点是固体润滑剂的供应过程和相关的转移过程。在第二个供资期，将利用这一认识综合固体润滑剂的概念。重点将放在机器元件和具有高负载滚动/滚子接触的驱动系统中的应用。

The vast majority of tribological systems in technical applications are lubricated with fluids, which are mostly oils and greases. In cases where lubrication with oil or grease is not possible because the lubricant evaporates in a vacuum, for example, a solid is often applied to the component surfaces as an alternative. The lubrication mechanism in solid layers is fundamentally different from tribosystems with fluids as lubricants. The complexity of the research subject requires an interdisciplinary approach in which methods of mechanical engineering and materials technology as well as physical and chemical simulation and analysis methods must be used in a specifically networked manner.Scientific goalsIn the priority program "Fluid-free lubrication systems with high mechanical loads", the mechanisms of friction and wear due to the formation of transfer layers in tribological systems with high mechanical loads when lubricated with solid lubricants are to be researched. In the first funding period, the focus was on the provision processes of the solid lubricant and the associated transfer processes. In the second funding period, the understanding will be used for the synthesis of solid lubricant concepts. The focus will be on applications in machine elements and in drive systems with highly loaded rolling/roller contacts.
