Research Abstract |
The tribological properties of lubricants under light-load mixed lubrication regime were evaluated by laboratory tribo-testers. A unique structure . activity relation" was observed, not only for steel but also for aluminum alloy and for anti-wear coatings under these conditions. The effective friction modifiers for each material were also found to depend on the material. The lubrication mechanism based on time dependent flexible boundary film was discussed from the chemical properties of lubricants and analysis of the rubbed surface.
