| Abstract: | The coefficient of friction and wear rate of poly(tetrafluoroethylene) filled with molybdenum disulphide, graphite, lead oxide, and basalt are determined. It is found that basalt decreases the wear rate 2000 times. The degree of crystallinity and other nucleation characteristics are also studied. It is estimated that the nucleation activity of basalt is 0.9. The specific surface energy at the melt/crystal interface is found to be 9 · 10−3 J/m2 and the adhesion energy between poly(tetrafluoroethylene) and basalt is 2 · 103 J/m2. |
