Abstract

The research presents the results of experimental determination of friction coefficient and linear wear at rubbing of graphite and boron nitride in the friction pair with materials of different types (steel 95X18, bronze BrAZh9-4, fluoroplastic F-4, polyamide PA-6, graphite MPG-7and hard alloy VK-8) under conditions of low speeds. It was found that the friction of polymers in pairing with layered solid lubricants is determined by tribotechnical properties of the polymer. The friction coefficient of layered solid-lubricating materials paired with metallic materials is determined by the quality of the forming adhesive ordered lubricating layer on the metal surface.
