“…shows that it occurs for silver at the interface. Thus, the bonding is weaker for ilver to sapphire, and this is consistent with the orbital energies and antibonding of figure 46. Silver has less antibonding energy than copper.…”

“…The excellent heat-transfer characteristics of the metallic counterpart contribute to this film formation during frictional processes in almost all polymers with viscoelastic properties. 6,12 The wear of spherulitic nylon is preceded by interfacial frictional heating and subsequent removal of the material and transfer to the counterface as well. Therefore, the wear resistance of nylon is attributed to its ability to form thin films while sliding against a steel counterpart.…”

ABSTRACT:Composites of nanometer-sized silica (SiO 2 ) filler incorporated in nylon-6 polymer were prepared by compression molding. Their friction and wear properties were investigated on a pin on disk tribometer by running a flat pin of steel against a composite disc. The morphologies of the composites as well as of the wear track were observed by scanning electron microscopy (SEM). The addition of 2 wt % SiO 2 resulted in a friction reduction () from 0.5 to 0.18 when compared with neat nylon-6. This low silica loading led to a reduction in wear rate by a factor of 140, whereas the influence of higher silica loadings was less pronounced. The smooth morphology obtained after the wear test indicated the negligible contribution to friction of the pin to the nanocomposite

“…Although their studies show transitions in friction and wear mechanisms at higher sliding temperatures, the reasons for these remain difficult to illustrate, and they become more pronounced under atmospheric sliding conditions. It is believed that close examination of the polyimide transfer behaviour 4 and the worn polymer surfaces will provide additional information on the changes in the material's physical or chemical structure under sliding. 5 Raman spectroscopy has rarely been used for in-depth analysis of the variation in the polyimide structure during sliding.…”

The use of post-mortem Raman spectroscopy in explaining friction and wear behaviour of sintered polyimide at high temperature

Due to their thermal stability and high strength, polyimides are an aromatic type of polymer that is used in sliding equipment functioning under high loads and elevated temperature. However, its tribological behaviour under high temperature and atmospheric conditions is not fully understood. It has been reported that a transition from high towards lower friction occurs 'somewhere' in the temperature region between 100°C and 200°C; however, a correlation with changes in the polyimide molecular structure remains difficult to illustrate and it is not certain whether or not this transition is correlated to lower wear. In the present work sliding experiments under controlled bulk temperatures between 100°C and 260°C are performed. A transition is observed in both friction and wear at 180°C which is further explained by microscopic analysis of the transfer film on the steel counterface and Raman spectroscopy of the worn polymer surfaces. A close examination of the spectra reveals transitions in relative intensity of certain absorption bands, pointing to different orientation effects of the molecular conformation at the polymer sliding surface at 180°C.
