報告簡介:
Organic additive molecules play an important rolein reductionof friction in boundary and mixed lubrication.These additives are able to adsorb on the sliding surfaces to avoid contact with the sliding surfaces. However, the adsorption mechanism and relationship between adsorption and friction properties are not well understood due to difficulty of measurement.Here, we report a novel method with vertical-objective-type ellipsometric microscopy (VEM) that enables ellipsometry to directly measure the thickness change of adsorbed films during the adsorption process and gap changes during sliding in-situ. The lubricating film formation abilities of adsorbed films with different conformations will be introduced.
