  • Thin Film Lubrication | SpringerLink

    The definition of different lubrication regimes is a historic problem (Jost et al. 2000).In boundary lubrication, molecules are absorbed on solid surfaces of a tribo-pair and form a mono-molecular absorbed layer as described by Hardy as shown in Fig. 1a.If the lubricant film thickness in the contact region is in a range from a few nanometers to tens of nanometers, different layers will be ...

  • (PDF) Thin film lubrication in the past 20 years

    2020-4-15 · notable simplification that arises in lubrication is the so-called “thin film” or “lubrication” approximation. The resulting Reynolds theory of lubrication is a constant viscosity, quasi two-dimensional theory, valid when the ratio of the characteristic lengths is vanishingly small.

    2018-12-12 · In thin-film lubrication (TFL), generally, the viscosity of the lubricant and its coefficient of friction (CoF) increase. Finding a method to reduce the CoF in TFL is a significant challenge for tribologists. In the present work, we report a robust superlubricity attained by using polyalkylene glycols (PAGs, polar molecules) and poly-α-olefins (PAOs, nonpolar molecules) as lubricants on steel ...
