Abstract

The properties of Xe, CH4 and C16H34 lubricant confined between two approaching solids were discussed. It was found that the layering transition tends to nucleate in disordered or imperfect regions in the lubrication film. The analysis showed that the squeeze process of lubricants was accompanied by phase transformations in the high-pressure region which allowed the confined surfaces to come closer and lower the elastic energy.
