Abstract
The results of an experimental study of the effect of the normal pressure in the range of 0.1–0.3MPa, a velocity of sliding of 1–100 mm/s, and a bulk temperature of 22 to–27°C on the coefficient of sliding friction of an elastomer–steel friction pair have been presented. Two types of elastomeric materials have been considered, i.e., frost-resistant rubber based on synthetic propylene oxide rubber and this rubber filled with the antifriction additive of ultrafine polytetrafluoroethylene powder in an amount of 1 weight part per 100 weight parts. The results have shown the efficiency of filling rubbers with ultrafine polytetrafluoroethylene; the coefficient of sliding friction at temperatures below–15°C decreases by more than two times.
