The Study of Tribological Properties of Composites Based on Phenylone and Hybrid Filler

摘要

The paper conveys the creation principles of hybrid composites for friction units, based on binder Phenylone C-2, filled with modified polyte-trafluoroethylene and inorganic nanoadditives, natural minerals, dispersed to a colloidal state. The optimal methods for modifying the fillers surface were selected in order to improve the adhesion strength at the components interface and to improve the properties of composite materials. The conducted tribological tests and morphological studies made it possible to optimize nanocomposites composition. It is shown that the dispersity increase of the filler leads to an improvement of tribocontact characteristics. Spectroscopic studies of the triboconjugation surface confirmed that the frictional film, formed on the friction surface, imparts high wear resistance and good antifriction properties to the friction unit.
