boundary lubrication

What Is Thin Film Lubrication? Thin film lubrication (TFL) is a lubrication regime with a film thickness of a few nanometers to tens of nanometers, which can be thought of as the lubrication regime between elastohydrodynamic lubrication (EHL) and boundary lubrication, or extended boundary lubrication. What is a lubrication film? Fluid film lubrication is the
