“…It is reasonable to expect quantitative changes in transfer film morphology and wear resistance using fillers of different chemical reactivity like C and CuS [10]. It is less obvious why such differences would emerge between different alumina-PTFE nanocomposites (Figure 2).…”

“…The adhesion strength between transfer films and counterfaces is among the most frequently discussed mechanisms of wear reduction for polymeric solid lubricants [3,[8][9][10][58][59][60][61][62]. Adhesion is often thought of in terms of bonding and may have physical or chemical origins [44,[63][64][65][66][67].…”

“…Incorporation of micro-scaled fillers has been shown to reduce wear rates of PTFE typically bỹ 100ˆwith >20 wt % filler loading [3,[6][7][8][9][10][11]. Early on, the wear-mitigating effect of these particles was attributed to preferential support of the normal load by the filler and disruption of subsurface crack propagation [6,12].…”

Abstract:In dry sliding conditions, polytetrafluoroethylene (PTFE) composites can form thin, uniform, and protective transfer films on hard, metallic counterfaces that may play a significant role in friction and wear control. Qualitative characterizations of transfer film morphology, composition, and adhesion to the counterface suggest they are all good predictors of friction and, particularly, wear performance. However, a lack of quantitative transfer film characterization methods and uncertainty regarding specific mechanisms of friction and wear control make definitive conclusions about causal relationships between transfer film and tribological properties difficult. This paper reviews the state of the art in the solid lubricant transfer film literature and highlights recent advances in quantitative characterization thereof.

“…Tanaka [13] concluded that the wear rate of polytetrofluroethylene (PTFE) was reduced when filled with ZrO 2 and TiO 2 . Bahadur et al [14][15][16] found that the compounds of copper such as CuO and CuS were very effective in reducing the wear rate of PEEK, PTFE, Nylon and HDPE. Kishore et al [17] studied the influence of sliding velocity and load on the friction and wear behaviour of G-E composite, filled with either rubber or oxide particles, and reported that the wear loss increased with increase in load/speed.…”

“…Fillers not only reduce the cost of the composites, but also meet performance requirements, which could not have been achieved by using reinforcement and resin ingredients alone. In order to obtain perfect friction and wear properties many researchers modified polymers using different fillers [12][13][14][15][16][17][18][19][20]. Briscoe et al [12] reported that the wear rate of highdensity polyethylene (HDPE) was reduced with the addition of inorganic fillers, such as CuO and Pb 3 O 4 .…”

The friction and wear behaviors of polyphenylene sulfide (PPS) filled with various particulate inorganic fillers were studied. The fillers were Ag 2 S, NiS, PbSe, and PbTe in varying proportions. Friction wear tests were performed in a pin-on-disc configuration at a sliding speed of 1.0 m s 01 and a load of 19.6 N. The pins were made of PPS-based composites and the discs of hardened tool steel. X-ray photoelectron spectroscopy (XPS) was used to study the interface of the transfer film and its steel substrate for the possible chemical changes occurring during sliding. It was found that Ag 2 S and NiS as the fillers decreased the wear rate of PPS very effectively, while PbSe and PbTe increased it dramatically. XPS analysis revealed that chemical reactions occurred during sliding between the fillers and the counterface metal iron in the cases of Ag 2 S and NiS, while there was no such chemical reaction when PbSe or PbTe was used as the filler. The chemical reactions in the cases of Ag 2 S and NiS contributed to enhancing the adhesion of transfer film to the counterface, and thus led to reduced wear. These observations led to the conclusion that the fillers that reduced wear had to be chemically active to the counterface metal. The Gibbs free energy criterion was suggested to test this hypothesis.
