| Outline of Final Research Achievements |
A new experimental system utilizing fluorescent microscopy technique has been developed to explore the basic friction and wear mechanism of polymeric materials. Sliding tests between polymer and glass counter face was conducted upon an inverted fluorescent microscope and dynamic behavior of the polymer transfer to the sliding counter face was visualized during sliding by capturing autofluorescence from transferred material. After the sliding tests, both morphological and quantitative transitions of the transfer film formation were extracted from fluorescent images and relationship between the dynamics of the polymer transfer film formation and frictional behavior could be discussed.
By using the established experimental procedure, effects of the surface profile of glass plates on friction between polyethelethelketone (PEEK) and glass were examined. If a stable PEEK transfer film with smaller amount could be elaborated on the glass surface, friction became stable and relatively low.
