Abstract
The paper discusses the tribological and physicomechanical properties of composites on the base of polytetrafluoroethylene and different grades of nanosize aluminum oxide powders as dependent on the filler content, technology of combining the ingredients, and operating temperature. It is shown that introduction of nanosize aluminum oxide significantly changes the triboengineering characteristics of the polymer, including the friction coefficient and temperature in the friction zone, which decrease and stabilize. The friction coefficient of the composite is found to decrease with increasing filler content.
