Abstract

The control of shear dependence through polymer thickening or base oil blending is employed to define a path to superlubricity with acceptable film thickness which utilizes common practices in the formulation of lubricants. Much work has already been done to characterize the effects of blending on pressure-viscosity response and shear-thinning. The present work provides an outline of the rheological properties required for superlubricity. Blending of base oils is preferred over polymer thickening to retain good film forming. The next step is the characterization of promising lubricant blends in high-pressure viscometers.

真实机器中的EHL超润滑

通过聚合物增稠或基础油混合来控制剪切依赖性，以确定具有可接受薄膜厚度的超润滑路径，该路径利用润滑油配方中的常用做法。已经做了大量的工作来表征共混对压力-粘度响应和剪切减薄的影响。本工作概述了超润滑所需的流变性能。混合基础油优于聚合物增稠以保持良好的成膜性。下一步是在高压粘度计中表征有前途的润滑油混合物。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
