Abstract

ABSTRACT

Molybdenum Disulfide (MoS) is the most widely used dry film lubricant (DFL) for moving mechanical assemblies that operate in space. For these applications, the MoS must provide low friction and wear across a range of temperatures. The temperature dependence of MoS tribological behavior has been studied previously. However, the number of temperatures and conditions that can be tested in a single study is necessarily limited, making it difficult to predict or understand the performance of DFLs more broadly. To address this, this review article summarizes and analyzes the results from prior studies of temperature-dependent tribological behavior of MoS-based dry film lubricants. Friction, wear, and wear life data are compiled into a plot matrix and trends are identified. Then, the mechanisms that have been proposed to explain observed trends are summarized. Finally, gaps in the knowledge and opportunities for future work are discussed such that researchers can build on existing studies to enhance the reliability and performance of MoS-based dry film lubricants in space environments.

摘要

二硫化钼（MoS₂）是用于在太空运行的移动机械组件的应用最为广泛的干膜润滑剂（DFL）。对于这些应用，MoS₂必须在一系列温度范围内提供低摩擦和低磨损性能。此前已对MoS₂摩擦学行为的温度依赖性进行了研究。然而，在一项单独研究中能够测试的温度和条件数量必然有限，这使得更广泛地预测或理解干膜润滑剂的性能变得困难。为解决这一问题，本文综述总结并分析了此前关于基于MoS₂的干膜润滑剂温度依赖性摩擦学行为研究的结果。将摩擦、磨损及磨损寿命数据整理成一个图表矩阵，并确定其中的趋势。然后，总结已提出的用于解释观察到的趋势的机制。最后，讨论了知识空白和未来工作的机会，以便研究人员能够在现有研究的基础上，提高基于MoS₂的干膜润滑剂在太空环境中的可靠性和性能。
