  • 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 ...
