“…The wear reducing mechanism of fillers in PTFE based composites till today remains a topic of debate and technological experiments [1,2]. Despite the wide and expanding use of solid lubrication in engineering design, there is an increasing demand for the new low friction, low wear materials to improve efficiency and operational life in various environments.…”

In present work it has been studied the physical-mechanical and tribological properties of the compositional material which was obtained in the PTFE base with chalcopyrite fine dispersed concentrate as fillers. The PTFE-chalcopyrite composites were prepared by powder metallurgy route containing chalcopyrite particles (2.5, 5 and 10 wt %). The tests have been performed in the friction machine under 0.7 MPa load where as a counterpart the gray cast iron was used. From the beginning, the weight wear was measured after passing some velocity steps (0.25-1.25 m/sec). The worn surfaces of the tested composites and the cast iron samples after working as a tribological pair were analyzed using SEM/EDX methods. The obtained results have shown that the incorporation of optimal quantity (~5 wt %) chalcopyrite particles into PTFE matrix drastically (>10 2 times) improves the wear resistance comparatively to the unfilled PTFE in the 0.25-1.25 m/sec friction velocity range. In the same testing conditions by the analysis of the obtained results it is determined that at the low velocity friction (<1 m/sec) the newly developed composite material has 10-15 times lower wear intensity than the best existing tribo-technical purpose commercial material "superfluvis", therefore the obtained composite can be considered as a quite inexpensive and efficient tribological material.

“…Some studies were made to show the effect of friction and wear of peek and its composites which were filled with fibers, inorganic fillers and polymers. One of the most effective fillers to reduce wear rate was PTFE [1][2][3]. SiC as filler is very important in reducing friction and wear.…”

Abstract:Friction By this work we can understand the effect of some nanometer particles which act as fillers in polyetheretherketone, and by this comparison study we conclude that friction and wear properties can be decreased or increased or stay unchanged by increasing and decreasing the amount of fillers but it can be improved by adding different fillers with certain properties to obtain optimal results.

“…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 . 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.…”

“…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 .…”
