Study of tribological properties of ecofriendly lubricant additives derived from leaf-surface waxes
Source abstract
Abstract
Three kinds of leaf-surface waxes are extracted from the leaves of Euonymus japonicas (EJ), Sabina chinensis (SC) and Sabina procumbens (SP) to be tested for their tribological properties. Lubricating oils containing these 3 waxes respectively were analyzed via gas chromatography-mass spectrometer (GC-MS) for their chemical constituents and tested with friction and wear testing machine and time of flight secondary ion mass spectrometry (TOF-SIMS) for the tribological mechanism. It was found that all the tested cuticular wax can reduce the coefficient of friction, and the waxes of SC and EJ can reduce the wear width. The contents of acid and esters in the wax can improve the friction reducing property by forming tribochemical films on the metal, but result in the increase of wear due to corrosion. The increase of ions containing C, H, O and the decline of aluminum positive ions on the worn surface, demonstrate that the tribofilms derived from long chain compounds play a role of protecting the metal surfaces.
